Free Mechanical Aptitude Test

This free Mechanical aptitude tests measures your knowledge of straightforward physical and mechanical concepts. Your score will depend significantly on your knowledge of:

If you are taking a mechanical aptitude test as part of the selection process for the emergency services or the military then the questions you can expect will tend to concentrate on principles rather than on making calculations. For example, you may be shown several diagrams of a lever and asked which one is the most efficient.

If however, you are taking a test for a technical job then you may be expected to calculate the actual force required to move a particular lever. In this case, knowing the principle is not enough, you need to know the formula.

If you need additional practice of mechanical tests after trying the questions below, we recommend AssessmentDay.

Many of the questions in mechanical comprehension tests are ‘industry’ specific. For example, tests used by the fire service tend to frame the questions in terms of fire-fighting whereas tests used to select for an aircraft maintenance job would tend to frame the questions in aviation industry terms.

It doesn’t matter if the questions you practice on aren’t specific to the industry you are applying for. It is the substance of the question that is important – the scenario is incidental.

Need further practice? If so, we recommend the mechanical test packages by AssessmentDay.

These sample question papers each contain 40 questions and have a suggested time limit of 30 minutes each. The questions are presented in Letter/A4 format for easy printing and self-marking.
