Question 1Design process and problem solving

Which statement best describes the main purpose of a design brief?

  1. It records the price paid for every material used in production.
  2. It lists the exact tools and machines needed to build the final product.
  3. It shows the finished product drawn to scale with full dimensions.
  4. It records the client's needs and the limits the solution must work within. Correct answer.

Explanation

A design brief is a short written statement that sets out the problem, the target user, the requirements and the constraints such as cost, time and safety. It guides all later work, so designers check their ideas against it before going further.

Question 2Design process and problem solving

A designer writes 'the lamp must weigh less than 1 kg and cost under B$30 to make'. What are these statements examples of?

  1. Ergonomic data
  2. Market research findings
  3. Design constraints Correct answer.
  4. Aesthetic judgements

Explanation

Constraints are fixed limits that any acceptable solution must respect, such as maximum mass or maximum cost. Because they can be measured and checked, they help designers judge whether an idea is workable before building it.

Question 3Design process and problem solving

During a design task, a student lists questions such as 'Who will use the product?' and 'Where will it be used?'. Which stage of the design process is the student working in?

  1. Generating possible solutions
  2. Evaluating the finished product
  3. Analysing the problem Correct answer.
  4. Planning the manufacture

Explanation

Analysing the problem means gathering information about users, context and requirements before ideas are produced. Asking who, where and why helps clarify the brief so that later solutions are relevant and properly targeted.

Question 4Design process and problem solving

Which technique is most likely to produce a wide range of early ideas in a short time?

  1. Producing a detailed working drawing
  2. Carrying out a strength test
  3. Running a group brainstorming session Correct answer.
  4. Writing a final evaluation

Explanation

Brainstorming encourages a group to offer many ideas quickly without judging them at first, which widens the search for solutions. Judgement and detailed drawing come later, when the ideas are sorted and developed.

Question 5Design process and problem solving

A designer sketches six rough ideas, then compares them against the brief and picks two to develop further. What is this step called?

  1. Patenting the ideas
  2. Screening the ideas Correct answer.
  3. Modelling the ideas
  4. Costing the ideas

Explanation

Screening means judging candidate ideas against the criteria in the brief so that weaker ones can be dropped early. This saves time and resources by concentrating development effort on the most promising concepts.

Question 6Design process and problem solving

What is the main purpose of building a scale model of a chair during the design process?

  1. To test how the full-size chair will behave
  2. To replace the need for any drawing
  3. To check appearance and proportions cheaply Correct answer.
  4. To show the client the final selling price

Explanation

A scale model lets designers and clients judge shape, proportion and appearance at low cost and before committing to full-size materials. It communicates the concept clearly, although it cannot replace full-size testing of strength.

Question 7Design process and problem solving

A prototype is best described as which of the following?

  1. A written report describing the design
  2. A final product ready for sale to customers
  3. A list of materials with their costs
  4. A first working version built to test an idea Correct answer.

Explanation

A prototype is an early working version made so that the design can be tested, handled and improved. Faults found in the prototype can be corrected before production begins, reducing waste and risk.

Question 8Design process and problem solving

Which action shows that a designer is evaluating a product against the original brief?

  1. Buying extra material in case of mistakes
  2. Choosing the most attractive colour for the packaging
  3. Comparing measured performance with the stated requirements Correct answer.
  4. Copying a popular design from a catalogue

Explanation

Evaluation compares what the product actually does with what the brief said it should do, using evidence such as measurements and user feedback. This shows whether the design has solved the stated problem.

Question 9Design process and problem solving

A firm asks users to try a new bottle and report how easy it is to open. Which kind of data is being collected?

  1. Quantitative data from instruments
  2. Primary data from the users themselves Correct answer.
  3. Theoretical data from calculations
  4. Secondary data from published reports

Explanation

Primary data are gathered first-hand from the people or situations being studied, so user feedback in a trial is primary data. It is valuable because it reflects real needs, although it must be collected from enough users to be reliable.

Question 10Design process and problem solving

In design work, what does the term ergonomics mainly concern?

  1. The cost of manufacturing a product
  2. The relationship between people and the products they use Correct answer.
  3. The choice of colour scheme for a product
  4. The strength of the material used

Explanation

Ergonomics studies how people interact with products, including reach, grip, posture and comfort, so that designs suit the human body. Good ergonomics reduces strain and makes a product safer and easier to use.

Question 11Design process and problem solving

A designer measures the hand span of 40 intended users before sizing a handle. Which design factor is being addressed?

  1. Intellectual property
  2. Anthropometrics Correct answer.
  3. Aesthetics
  4. Batch production

Explanation

Anthropometrics is the collection and use of body measurements so that products fit the range of users. Measuring many people gives a size that suits most of the target group rather than only the designer.

Question 12Design process and problem solving

Which pair of words correctly describes a specification that states 'must fit a 300 mm shelf' rather than 'should look attractive'?

  1. Objective rather than subjective Correct answer.
  2. Qualitative rather than quantitative
  3. Decorative rather than functional
  4. Subjective rather than objective

Explanation

An objective specification can be measured and checked, such as a 300 mm limit, while a subjective one depends on personal opinion, such as attractiveness. Objective criteria make it possible to judge fairly whether a design meets its brief.

Question 13Design process and problem solving

A designer wants to know whether a new kettle handle becomes too hot in use. Which test gives the most useful evidence?

  1. Reading the manufacturer's warranty
  2. Weighing the kettle when it is empty
  3. Measuring the handle temperature after boiling Correct answer.
  4. Asking a friend whether the handle looks safe

Explanation

Measuring the handle temperature after boiling gives objective evidence that can be compared with a safe limit. Physical measurement shows what actually happens in use, whereas opinions only describe impressions.

Question 14Design process and problem solving

Which statement is the clearest example of a well-written design specification point?

  1. The product must be attractive to everyone who sees it.
  2. The product should be nice and easy to carry around.
  3. The product should be made from good quality stuff.
  4. The product must have a handle at least 120 mm long. Correct answer.

Explanation

A good specification point is specific and measurable so that it can be tested, and a stated handle length meets that rule. Vague words such as nice or good cannot be checked and so are poor criteria.

Question 15Design process and problem solving

A team writes down every step needed to turn a chosen design into a finished product, with times and materials. What have they produced?

  1. A production plan Correct answer.
  2. A design brief
  3. A mood board
  4. A risk assessment

Explanation

A production plan sets out the sequence of operations, the materials, the tools and the time needed to make the product. It helps the team work efficiently and spot problems such as missing materials before work starts.

Question 16Design process and problem solving

Before cutting material, a student identifies hazards, decides who might be harmed and notes how to reduce the risk. Which document is the student completing?

  1. A quality control chart
  2. A cutting list
  3. A design brief
  4. A risk assessment Correct answer.

Explanation

A risk assessment identifies hazards, the people exposed to them and the measures that reduce the risk. Completing it before work begins helps prevent accidents in the workshop.

Question 17Design process and problem solving

A designer makes a full-size cardboard mock-up of a storage unit before cutting timber. What is the main benefit of this step?

  1. It checks size and fit before costly material is used. Correct answer.
  2. It removes the need for any measurement.
  3. It proves the timber joints will be strong enough.
  4. It gives a finished surface for the final product.

Explanation

A full-size mock-up in cheap material shows whether the unit is the right size and fits its space before expensive timber is cut. Mistakes found at this stage cost little to correct compared with errors in the final material.

Question 18Design process and problem solving

A designer notices that users keep gripping a tool in an awkward way. Which response best shows analysis of this observation?

  1. Adding a bright colour to the tool handle
  2. Increasing the size of the packaging
  3. Reducing the price of the tool
  4. Investigating the grip shape and hand position of users Correct answer.

Explanation

Analysing an observation means finding out why the problem occurs, such as an unsuitable grip shape for the users' hands. The findings then guide a change to the design rather than an unrelated alteration.

Question 19Design process and problem solving

Which statement best explains why designers keep a record of rejected ideas in their design folder?

  1. It proves that the final idea was the first one considered.
  2. It shows the range of thinking and the reasons for decisions. Correct answer.
  3. It guarantees the product will sell well.
  4. It replaces the need for testing the chosen design.

Explanation

Recording rejected ideas with the reasons for rejection shows how the designer reached the final choice and demonstrates a thorough process. It also allows earlier ideas to be revisited if the chosen one fails later.

Question 20Design process and problem solving

A designer sets a target that the finished product must survive a drop from 1 m onto a hard floor. At which stage should this target be written?

  1. During the final evaluation
  2. In the advertising material
  3. In the specification, before development Correct answer.
  4. Only after the product has broken

Explanation

Performance targets belong in the specification so that they guide development and give a clear test for later evaluation. Writing them before development prevents the designer from adjusting the goal to match whatever was built.

Question 21Design process and problem solving

Two designs meet the brief, but design A uses 30 percent less material and needs fewer processes. Which conclusion is best supported?

  1. Design A is likely to be cheaper and more sustainable to produce. Correct answer.
  2. Design B is certain to be more popular with users.
  3. Design A will certainly be stronger in use.
  4. Design B must have been tested less thoroughly.

Explanation

Using less material and fewer processes usually lowers cost and reduces waste and energy use, so design A has clear production advantages. Strength and popularity are separate questions that would need their own tests and evidence.

Question 22Design process and problem solving

A designer plans to test three handle shapes with ten users each and record comfort scores. Which aspect of the design process does this plan represent?

  1. Collecting evidence to compare solutions Correct answer.
  2. Costing the production of the handles
  3. Writing the initial design brief
  4. Producing the final working drawings

Explanation

Testing several solutions with users and recording scores gathers evidence for comparing them fairly. This turns an opinion about comfort into data that can guide the choice of the best handle.

Question 23Design process and problem solving

A client asks for a product that is both extremely cheap and made from solid hardwood. Why should the designer raise this with the client?

  1. The two requirements may conflict and need to be balanced. Correct answer.
  2. Cheap products cannot be sold in shops.
  3. Hardwood is always unsuitable for any product.
  4. Clients are not allowed to state requirements.

Explanation

Requirements can conflict, and solid hardwood is usually expensive, so meeting a very low cost target may be impossible. The designer should discuss the trade-off with the client so that realistic priorities are agreed early.

Question 24Design process and problem solving

A designer keeps a simple chart listing each requirement, the test used and a pass or fail result. What is the main value of this chart?

  1. It gives a clear, checkable record of how the design meets the brief. Correct answer.
  2. It shows the selling price of each unit.
  3. It lists the names of the workers involved.
  4. It replaces the need to build a prototype.

Explanation

A chart linking each requirement to a test and a result gives clear evidence of whether the brief has been met. It makes gaps and failures visible so that they can be corrected before production.

Question 25Design process and problem solving

A student writes 'the toy must be safe for a three-year-old' in the brief. Which later action best turns this broad aim into something testable?

  1. Asking the client to sign the brief
  2. Adding the toy to a catalogue
  3. Choosing a bright colour for the toy
  4. Listing measurable checks such as no small parts that fit a test gauge Correct answer.

Explanation

A broad aim becomes testable when it is broken into measurable checks, such as the absence of small parts that fit a standard gauge. These checks can then be applied to the prototype and the results recorded.

Question 26Design process and problem solving

Which statement best describes the purpose of a design brief?

  1. A short statement of the problem, the intended user and the main constraints Correct answer.
  2. A detailed list of every measurement and material the product will use
  3. A drawing of the finished product prepared for the client to approve
  4. A record of the tests carried out on the first working model

Explanation

A brief sets out the problem to be solved, who it is for and the key limits the designer must respect. It comes before detailed decisions are made, so it stays broad and open. Measurements, materials and drawings belong to later specification and development work.

Question 27Design process and problem solving

A designer lists every task needed to move from an agreed design to a finished product, showing the order of tasks, the time each takes and who does it. Which planning tool has been produced?

  1. A Gantt chart Correct answer.
  2. A feedback form
  3. A mood board
  4. A specification

Explanation

A Gantt chart displays tasks as bars along a timeline, so overlapping work, durations and responsibilities can be seen at a glance. It is a scheduling tool used to manage the making stage. Mood boards, specifications and feedback forms serve different purposes.

Question 28Design process and problem solving

During evaluation, a designer compares measured test results with the targets written in the specification. Which outcome shows that the design needs further development?

  1. Every measured value falls inside the stated target range
  2. The product matches the appearance sketched in the brief
  3. Users say they prefer it to a rival product on the market
  4. Most values pass, but one important target is clearly missed Correct answer.

Explanation

Evaluation judges performance against the specification, so a missed target is direct evidence that the design does not yet fully meet the brief. Preference over a rival or a match with the sketch does not show that stated targets were achieved. Further development is justified whenever a requirement fails.

Question 29Design process and problem solving

A designer generates a wide range of quick outline ideas on paper before choosing one to develop. Which reason best explains why this stage is kept broad and unrestrained?

  1. It produces a neat presentation sheet for the client to sign
  2. It reduces the number of materials that will be needed later
  3. It guarantees the first idea chosen will be the best one
  4. It allows unusual solutions to emerge before judgements are made Correct answer.

Explanation

Divergent thinking separates the generation of ideas from the judging of them, so early criticism does not cut off promising possibilities. A wide range increases the chance of finding an original approach that later analysis can refine. Judging too soon narrows the search and tends to produce conventional results.

Question 30Design process and problem solving

A designer builds a simple physical model to check whether a folding mechanism opens smoothly and locks securely, using cheap materials and rough joints. Which statement best justifies this approach?

  1. The rough finish shows the client exactly how the manufactured product will look
  2. The model isolates the mechanism's behaviour so it can be judged before detailed styling and finish are decided Correct answer.
  3. The cheap materials guarantee the mechanism will behave identically in the final material
  4. The model proves the final product will pass all safety standards without further testing

Explanation

A focused model tests one uncertain aspect of a design in isolation, which keeps the work quick and cheap while giving useful evidence. Judging the mechanism early allows faults to be corrected before expensive styling and production decisions are fixed. A rough model cannot confirm standards compliance or final appearance.

Question 31Materials and their properties

Which property describes a material's ability to be hammered or rolled into thin sheets without cracking?

  1. Elasticity
  2. Ductility
  3. Malleability Correct answer.
  4. Brittleness

Explanation

Malleability is the capacity of a material to deform permanently under compressive force, allowing it to be shaped into thin sheets. Metals such as aluminium and copper are highly malleable, which is why they can be rolled into foil. Ductility instead concerns stretching into wire, while brittleness means fracturing without deformation.

Question 32Materials and their properties

A material that allows heat to pass through it quickly is best described as which of the following?

  1. A thermal insulator
  2. A thermal conductor Correct answer.
  3. A dielectric
  4. A refractory material

Explanation

A thermal conductor transmits heat energy readily through its structure because free electrons and closely packed particles transfer energy quickly. Metals such as copper and aluminium are good conductors and are used for cooking pans. Insulators, by contrast, trap air or have few free electrons and slow heat transfer.

Question 33Materials and their properties

Which material is obtained from the trunk of a tree and used in furniture and building work?

  1. Timber Correct answer.
  2. Clay
  3. Leather
  4. Wool

Explanation

Timber is the wood harvested from trees and is classed as a natural material used for furniture, frames and joinery. Leather comes from animal hides, clay is dug from the ground and wool is shorn from sheep. Only timber originates from the trunk of a tree.

Question 34Materials and their properties

Which of these is a thermoplastic that softens when heated and can be reshaped repeatedly?

  1. Bakelite
  2. Polystyrene Correct answer.
  3. Melamine
  4. Vulcanised rubber

Explanation

Thermoplastics have long chain molecules held by weak forces that loosen on heating, so the material softens and can be remoulded many times. Polystyrene behaves in this way and is easily recycled by melting. Thermosetting plastics such as Bakelite and melamine cross-link and cannot be remelted.

Question 35Materials and their properties

A metal that contains iron as its main element is classified as which type of material?

  1. A non-ferrous metal
  2. A noble metal
  3. A ferrous metal Correct answer.
  4. An alloy of copper

Explanation

Ferrous metals are those whose principal constituent is iron, which gives them magnetic properties and a tendency to rust. Examples include mild steel, cast iron and wrought iron. Non-ferrous metals such as copper and aluminium contain no significant iron.

Question 36Materials and their properties

Which property allows a material to be drawn out into a long thin wire?

  1. Opacity
  2. Hardness
  3. Density
  4. Ductility Correct answer.

Explanation

Ductility is the ability of a material to undergo plastic deformation under tensile force, letting it be pulled into wire. Copper is very ductile and is drawn into cables for electrical wiring. Hardness, opacity and density do not describe stretching into wire.

Question 37Materials and their properties

Which of the following is a composite material made by combining glass fibres with a plastic resin?

  1. Cast iron
  2. Glass-reinforced plastic Correct answer.
  3. Acrylic sheet
  4. Mild steel

Explanation

Glass-reinforced plastic, often called fibreglass, combines glass fibres for strength with a polyester or epoxy resin that binds them. The two constituents together give properties neither has alone. Steel, acrylic and cast iron are single materials rather than composites.

Question 38Materials and their properties

Which material is a natural fibre commonly woven into fabric for clothing?

  1. Nylon
  2. Polyvinyl chloride
  3. Cotton Correct answer.
  4. Polyester

Explanation

Cotton is a natural fibre harvested from the seed hairs of the cotton plant and is spun and woven into fabric. Nylon, polyester and PVC are all manufactured polymers made from petrochemicals. Only cotton is a naturally occurring textile fibre.

Question 39Materials and their properties

A designer needs a material for a saucepan handle that will not become too hot to hold. Which property should be maximised?

  1. Thermal conductivity
  2. Thermal insulation Correct answer.
  3. Malleability
  4. Electrical conductivity

Explanation

A handle must resist the transfer of heat from the pan to the hand, so the material should be a good thermal insulator. Materials such as Bakelite or wood have low thermal conductivity and keep the grip cooler. High conductivity would carry heat quickly to the user.

Question 40Materials and their properties

Why is aluminium preferred to steel for the body of an aircraft?

  1. It is cheaper to mine than iron ore
  2. It has a higher strength-to-weight ratio Correct answer.
  3. It melts at a lower temperature
  4. It is harder than steel

Explanation

Aluminium alloys give useful strength while being far less dense than steel, so an aircraft structure can be lighter and more fuel efficient. The key advantage is strength relative to weight rather than cost or melting point. Lower melting point and lower hardness would not be advantages in this application.

Question 41Materials and their properties

A workshop stores steel tools in a damp shed and they begin to rust. Which material property is responsible?

  1. The steel has become brittle
  2. The tools have lost their elasticity
  3. Corrosion resistance is low in ferrous metals Correct answer.
  4. The tools have absorbed water into their grain

Explanation

Iron in steel reacts with oxygen and moisture to form hydrated iron oxide, so ferrous metals with low corrosion resistance rust in damp conditions. Protection such as painting, oiling or galvanising is needed. Rusting is a surface chemical reaction rather than a change to brittleness or elasticity.

Question 42Materials and their properties

Which plastic would be most suitable for a washing-up bowl that must withstand hot water and repeated impact?

  1. Cellulose acetate film
  2. Polystyrene foam
  3. Polypropylene Correct answer.
  4. Silicone sealant

Explanation

Polypropylene is a tough thermoplastic with good resistance to hot water and repeated flexing, which suits a bowl. Foamed polystyrene is weak and insulating rather than structural, thin film lacks rigidity and silicone sealant is not a moulded bowl material. The choice depends on matching toughness and heat resistance to the task.

Question 43Materials and their properties

A manufacturer wants a component that can be moulded into a complex shape once and will not soften in service. Which class of plastic should be chosen?

  1. An elastomer
  2. A thermosetting plastic Correct answer.
  3. A natural resin
  4. A thermoplastic

Explanation

Thermosetting plastics cure into a rigid cross-linked network that cannot be remelted, so they hold complex moulded shapes even when warm. Thermoplastics would soften again on heating and elastomers stay rubbery. The curing behaviour of thermosets matches the requirement.

Question 44Materials and their properties

Brass is made by combining copper with which other metal?

  1. Tin
  2. Zinc Correct answer.
  3. Lead
  4. Nickel

Explanation

Brass is an alloy of copper and zinc, and varying the zinc content changes its colour and hardness. Adding tin to copper produces bronze instead. Lead and nickel may appear in specialist alloys but are not the defining addition in brass.

Question 45Materials and their properties

Which property is most important for a material used to make a safety helmet shell?

  1. High water absorbency
  2. High impact resistance Correct answer.
  3. High electrical conductivity
  4. Low melting point

Explanation

A helmet shell must absorb and spread the energy of an impact without cracking, so toughness and impact resistance are essential. Conductivity, absorbency and a low melting point would not protect the wearer and could be harmful. Material selection therefore centres on mechanical toughness.

Question 46Materials and their properties

A wooden chair leg splits along the grain when a heavy load is applied. Which property of the timber is being tested?

  1. Hardness of the end grain
  2. Compressive strength along the grain
  3. Shear strength along the grain Correct answer.
  4. Tensile strength across the grain

Explanation

When a leg splits along the grain, the failure is by sliding of fibres past one another, which is a shear failure. Timber is weakest in shear parallel to the grain, so joints and loads must be designed with this in mind. Compression along the grain would cause crushing rather than a split.

Question 47Materials and their properties

Which material would be chosen for an electrical plug casing because it does not conduct electricity?

  1. An insulating plastic such as urea formaldehyde Correct answer.
  2. Copper
  3. Graphite
  4. Aluminium

Explanation

A plug casing must insulate the user from live conductors, so a material with high electrical resistance is needed. Urea formaldehyde is a rigid thermoset with good insulating properties and heat resistance. Copper, aluminium and graphite all conduct electricity and would be dangerous.

Question 48Materials and their properties

A product must flex repeatedly without permanent deformation and then return to its original shape. Which property is required?

  1. Malleability
  2. Plasticity
  3. Elasticity Correct answer.
  4. Brittleness

Explanation

Elasticity is the ability of a material to recover its original shape once a load is removed, which is essential for springs and flexible seals. Plasticity and malleability involve permanent deformation, and brittleness means fracture. Only elasticity describes repeated recovery of shape.

Question 49Materials and their properties

A garden bench is to be made from timber and left outdoors all year. Which property matters most in choosing the species?

  1. Brightness of colour
  2. Low density
  3. High absorbency
  4. Durability against decay Correct answer.

Explanation

Outdoor timber is exposed to rain, fungi and insects, so natural durability against decay is the key selection factor. Species such as teak or oak resist rot better than softwoods. Colour, density and absorbency matter less than resistance to biological attack.

Question 50Materials and their properties

Which statement best explains why a composite can outperform its individual constituents?

  1. The matrix dissolves the fibres to spread stress
  2. Reinforcing fibres carry load while the matrix binds and protects them Correct answer.
  3. The constituents melt together into a single new element
  4. The composite always has a lower density than either part

Explanation

In a composite the strong fibres carry most of the tensile load while the matrix holds them in place, spreads stress between them and shields them from damage. The two materials act together rather than forming a new element. This combination gives stiffness and strength that neither part provides alone.
