Free Mechanical Reasoning Test
A free mechanical reasoning test in the format used by employers and the trades — diagram questions on gears, levers, pulleys and forces. Instant score, a breakdown by topic, and an explanation of the physics for every answer.
What a mechanical reasoning test measures
Mechanical reasoning tests check how well you understand everyday physical principles — how gears, levers, pulleys and forces behave. They are widely used in the trades, engineering, manufacturing, emergency services and the armed forces, where working safely with machinery matters.
The topics it covers
| Topic | What to know |
|---|---|
| Gears | Meshed gears turn opposite ways; a smaller gear turns faster; a belt drives wheels the same way. |
| Levers | A longer lever arm needs less force; a beam balances when weight × distance is equal on both sides. |
| Pulleys | A fixed pulley only changes direction; each extra supporting rope shares the load. |
| Forces & machines | Ramps trade force for distance; parallel springs share a load; gearing down trades speed for torque. |
How to prepare
Learn the handful of core rules above until they are automatic, then practise reading each diagram carefully — most mistakes come from misreading the picture, not the physics. Reviewing the explanation for every item, as this test gives you, builds that habit fast.
More aptitude practice
Mechanical reasoning pairs naturally with the spatial reasoning test (visualising shapes) and the abstract reasoning test (spotting patterns).
This test is for practice and self-assessment. It is not an official aptitude exam; your result estimates your skill on these questions.
Frequently asked questions
What is a mechanical reasoning test?
A mechanical reasoning test measures how well you understand basic physical and mechanical principles — gears, levers, pulleys, forces and simple machines — usually through diagram questions. It is common in trades, engineering, manufacturing and armed-forces selection.
What does a mechanical reasoning test cover?
The usual topics are gears (direction and speed), levers and balances (moments), pulleys (force advantage), and forces and simple machines (ramps, springs, torque). This test covers all four and scores each separately.
How can I prepare for a mechanical reasoning test?
Learn a few core rules cold: meshed gears turn opposite ways, a longer lever arm needs less force, weight × distance balances a beam, and a movable pulley roughly halves the effort. Practising with explanations, as this test provides, is the fastest way to improve.
Is the mechanical reasoning test free?
Yes. It is completely free, needs no sign-up, and your answers stay in your browser — only your best score is saved locally so you can retake it.
