MATSEC SEC Engineering Technology study plan

List the ten workshop hazard categories (mechanical, electrical, chemical, fire, manual handling, noise, dust, slips, eye, hand) and match each to a specific control measure you would apply at a bench or machine station.

Write out the correct PPE selection for five named tasks: arc welding, pedestal drilling, lathe turning, soldering, and solvent degreasing.

Distinguish between a hazard, a risk and a control, and use that vocabulary to complete a short risk assessment (likelihood x severity matrix) for a single workstation.

Classify twelve given engineering materials as ferrous, non-ferrous, polymer, ceramic or composite, and state one typical workshop use for each.

Define and give one worked example of each mechanical property: tensile strength, hardness, ductility, malleability, brittleness, toughness, elasticity and fatigue resistance.

Explain the effect of carbon content on the properties of plain carbon steel and name the property changes produced by annealing, normalising, hardening and tempering.

Describe the purpose and typical procedure of the tensile test, the hardness test (Brinell/Vickers) and the impact test, and interpret a simple stress-strain curve by labelling yield point, UTS and fracture.

Identify the main parts of a centre lathe and a vertical milling machine and state the function of each part.

Select appropriate cutting tool materials (HSS, carbide, ceramic) for given workpieces and justify the choice in one sentence each.

Calculate spindle speed from the formula N = 1000V/(pi x D) for three given combinations of cutting speed and diameter.

Describe the sequence of operations to turn a stepped shaft between centres, naming each operation and the tool used.

Distinguish between up-milling and down-milling, and between slab milling, slot milling and face milling, with a sketch-free written description of each.

Explain the purpose of drilling, reaming, boring, counterboring, countersinking and tapping, and state when each is chosen over the others.

List the safety rules specific to rotating machinery, including chuck key discipline, guarding, swarf handling and never measuring while the work rotates.

Identify five common machining faults (chatter, poor surface finish, tool wear, oversize hole, work deflection) and state one corrective action for each.

Produce third-angle orthographic views (front, plan, side) from a supplied isometric description of a simple bracket, applying correct line weights and hidden-detail conventions.

Apply dimensioning rules correctly: no duplicated dimensions, dimensions to features not to hidden lines, and consistent use of arrowheads, leaders and radius/diameter symbols.

Draw and correctly label a full section view, and explain the difference between a section, a half section and a revolved section.

Interpret the main ISO/BS 8888 drawing conventions including line types, projection symbols, tolerances and surface finish symbols.

Explain the role of layers, blocks and model versus paper space in CAD, and describe the workflow from 3D model to dimensioned 2D drawing.

Read and interpret a simple assembly drawing, identifying the parts list, item numbers and the function of each component.

Select the correct measuring instrument for five scenarios and state its resolution and typical accuracy: steel rule, vernier caliper, micrometer, dial test indicator, engineer's square.

Read a vernier caliper and a metric micrometer to 0.02 mm and 0.01 mm respectively from written scale readings you generate yourself.

Describe the correct use and care of hand tools: files, hacksaws, taps and dies, chisels, and the consequences of misuse such as a glazed file or a broken tap.

State the safety precautions for portable power tools, including 110 V site supply, RCD protection, blade guarding and dust extraction.

Compare oxy-acetylene welding, MIG, TIG and resistance welding on heat source, typical materials, typical thickness, and one advantage and one limitation each.

Distinguish soldering from brazing by temperature range, filler type and joint strength, and state the correct flux and cleaning procedure for each.

Select an appropriate adhesive for metal, plastic, wood and glass joints and explain surface preparation and cure requirements.

Name and describe six mechanical fasteners and state one application where each is preferred over welding.

Identify the four-bar linkage, crank-slider, cam and follower, and gear train in written descriptions, and calculate the velocity ratio of a simple and a compound gear train.

Calculate the mechanical advantage, velocity ratio and efficiency of a lever, pulley system, screw jack and inclined plane from given dimensions.

Explain belt, chain and gear drives and state the practical reason each is chosen, including slip, maintenance and centre-distance constraints.

Apply Ohm's law and series/parallel resistor rules to five worked circuit problems, showing units at every step.

Distinguish AC from DC, state typical domestic supply values, and explain the function of a fuse, MCB, RCD and earth conductor.

Describe the operation of a simple control system using a sensor, a controller and an actuator, and give one engineering example of open-loop and one of closed-loop control.

Identify common electronic components from a written description (resistor, capacitor, diode, LED, transistor, relay) and state the function of each.

Write a project plan for a small engineered product covering specification, design, materials selection, manufacturing sequence, cost estimate and evaluation against the original brief.

Produce a Gantt-style schedule with at least eight tasks, dependencies and realistic durations for your project.

Explain how design choices affect sustainability: material selection, recyclability, energy in manufacture, product life and end-of-life disposal.

Describe the environmental impact of three manufacturing processes and one joining process, and propose one mitigation for each.

Complete a full timed mock paper under exam conditions and review every incorrect answer to identify the underlying misconception.
