Compute reactions at supports for simply supported, cantilever and overhanging beams carrying point loads and uniformly distributed loads, showing free-body diagrams for every case.

Explain the difference between first-angle and third-angle projection in writing and identify which convention a given drawing uses from the placement of views alone.

Calculate centroid and second moment of area for at least four composite sections (T, I, L, hollow rectangle) and use them to find bending stress in a simply supported beam.

Determine friction forces on horizontal and inclined planes, including the angle of repose, and verify one result experimentally with a simple inclined-plane setup.

Describe the sequence of operations for turning, drilling, milling and shaping, and match each process to the type of surface it produces.

Identify five common workshop hand tools and three machine tools, state the safety precautions for each, and describe one typical fault and its remedy.

Select cutting speeds and feeds for turning and drilling operations on mild steel and aluminium, showing the calculation for spindle speed.

Apply Ohm's law, Kirchhoff's laws and series-parallel reduction to solve at least twelve DC circuits, checking each answer by a second method.

Analyse single-phase AC circuits containing resistance, inductance and capacitance, calculating impedance, current, power factor and phase angle.

Explain the operating principle of a transformer and a DC machine, and calculate transformer turns ratio and secondary current for three worked examples.

State the first and second laws of thermodynamics and apply them to closed-system problems involving work, heat and internal energy change.

Compute the thermal efficiency of a simple Rankine or Carnot cycle given operating temperatures, and explain why practical efficiency falls short.

Trace the energy conversions in a four-stroke engine and a steam power plant, and calculate indicated power, brake power and mechanical efficiency from given data.

Compare conduction, convection and radiation heat transfer, and solve three composite-wall or lagging problems using the appropriate resistance network.

Describe welding, brazing and soldering processes, distinguish their temperature ranges and filler behaviour, and state one inspection method for each.

Explain casting and moulding processes, including pattern allowances and causes of common casting defects, and propose a remedy for three defects.

Evaluate the environmental and efficiency trade-offs between two energy sources used for electricity generation in the local context, in a written argument of at least 250 words.

Select appropriate instruments for measuring length, angle, temperature, pressure and flow, and state the range, resolution and typical uncertainty for each.

Explain the construction and use of a vernier caliper, micrometer and dial gauge, and calculate least count and reading including zero error correction for five sample readings.

Describe open-loop and closed-loop control with block diagrams, and identify the sensor, controller and actuator in three practical systems.

Calculate stresses and strains in simply supported beams, columns and short struts, and check a column against Euler buckling for a given end condition.

Describe the components and construction sequence of a reinforced concrete beam and a brick masonry wall, including the purpose of each reinforcement bar.

Interpret a simple structural or site plan well enough to list quantities of concrete, brick and steel for one small element.

Produce a fully dimensioned 2D CAD drawing of a mechanical part, setting layers, line types, dimension style and title block to a consistent standard.

Create a 3D CAD model of the same part and generate orthographic and isometric views from the model, then compare them with the hand-drawn version.

Carry out a risk assessment for one workshop task using a likelihood-by-severity matrix, and list control measures in order of priority.

Identify the legal and professional duties of an engineering technologist in the local context, including duties to employer, public and environment, and describe the consequences of negligence.

Outline the stages of an engineering project from brief to handover, and state the purpose of specifications, drawings, schedules and inspection records at each stage.

Attempt a full timed mock paper covering all ten domains under exam conditions, then mark it against the syllabus and record the score per domain.

Re-work every question missed in the mock, writing the correct method and the reason for the original error beside each one.

Revisit the three weakest domains from the mock and solve ten additional problems in each within a two-hour block.

Assemble a one-page formula and data sheet from memory, then check it against source notes and correct any gaps.

Recite the standard safety, drawing-convention and professional-practice points that recur across domains, confirming each from notes rather than recall alone.
