The skill
What is a mechanical reasoning test?
A mechanical reasoning test presents a physical system and asks what will happen. Questions rely on practical principles such as force, leverage, pressure, motion, electricity and mechanical advantage rather than advanced mathematics.
Employers use these tests to assess applied physical understanding and the ability to reason about equipment, maintenance and technical situations.
Question formats
What do the questions look like?
Most items combine a diagram with a short question and several options. The same principle may appear in different-looking systems, so learning the underlying rule is more useful than memorising pictures.
- Levers, moments and balance
- Gears, belts and rotational direction
- Pulleys and mechanical advantage
- Pressure, fluids and buoyancy
- Basic circuits, heat and motion
Two meshed gears have different diameters. You determine which direction the second gear turns and which gear completes more rotations in the same period.
Launch coverage
Which providers use mechanical reasoning tests?
Cognivy covers SHL-style mechanical comprehension, Aon scales mtu-style content, Pearson TalentLens Bennett-style preparation and Saville-style mechanical reasoning as separate provider routes.
Provider names identify the assessment format. Cognivy is independent and is not affiliated with or endorsed by these providers.
A clear route
How should you prepare?
- 1
Learn one physical principle at a time with a clear diagram.
- 2
Predict the direction or effect before looking at answer options.
- 3
Explain each answer in terms of the principle, not visual intuition.
- 4
Mix visually different questions that use the same rule.
- 5
Finish with timed sets matching the target provider's breadth.
Cognivy uses your assessment date to choose the route. It does not ask you to predict a permanent study schedule. When you sit down to practise, choose the session length that fits that day.
What slows progress
Common mistakes
- Relying on how a diagram feels instead of a physical rule
- Memorising one illustration rather than transferring the principle
- Missing the effect of size, distance or direction
- Using unnecessary calculations where a qualitative comparison is enough
