Mechanical engineering

About this practice suite

This suite prepares candidates for mechanical engineering selection in the engineering, technical, and design sector with 5 skill areas: mechanical comprehension, technical reasoning, numerical reasoning, situational judgment and spatial reasoning. 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.
• Technical reasoning — Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Situational judgment — Evaluating workplace responses against role-relevant principles.
• Spatial reasoning — Rotation, folding, views, orientation, maps, and three-dimensional visualization.

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 mechanical engineer's primary design duty is to:

   • A. Specify machines and systems that meet load, efficiency, and safety requirements
   • B. Draft only architectural floor plans
   • C. Sell spare parts exclusively
   • D. Ignore material selection

2. Prototype shaft shows unexpected fatigue cracks at a sharp shoulder. What is best?

   • A. Delete FEA results
   • B. Polish cracks and ship
   • C. Increase speed only
   • D. Reduce stress concentration with fillet radius and reassess life

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.
