Military mechanical aptitude

About this practice suite

This suite prepares candidates for military mechanical aptitude selection in the military and defence sector with 5 skill areas: mechanical comprehension, spatial reasoning, numerical reasoning, technical reasoning and safety judgment. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

• Mechanical comprehension — Forces, motion, gears, pulleys, levers, fluids, pressure, and basic machines.
• Spatial reasoning — Rotation, folding, views, orientation, maps, and three-dimensional visualization.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Technical reasoning — Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
• Safety judgment — Hazard recognition, safe sequencing, escalation, and risk controls.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.

1. A lever lifts 600 N load with 200 N effort. Ideal mechanical advantage is:

   • A. 3
   • B. 120000
   • C. 0.33
   • D. 800

2. Which simple machine changes force direction without ideal MA of 2?

   • A. Inclined plane
   • B. Two movable pulleys in ideal block
   • C. Gear train 2:1
   • D. Single fixed pulley

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
