What are mechanical reasoning tests and when are they used?

Mechanical reasoning tests are generally used during the selection or recruitment process for jobs related to engineering, the emergency services and the army, amongst many others. They are typically used to assess how well an individual can apply reasoning in a practical environment.

Candidates will often be required to answer questions based on a variety of topics, such as: Electrical circuits, Pulleys, Levers, Springs, Tools, Gears and Maps. It is important that you have a good knowledge of each of these areas, and the basic principles within them; although it is highly unlikely that candidates would have reached this stage of recruitment without any knowledge or experience of these.

Candidates typically receive an image depicting a mechanical scenario or problem, likely to include kinetic/potential energy, friction and forces etc., for which a related question will be asked. In some questions, candidates may also need to identify the most appropriate tool to use in order to complete a specific job. Mechanical reasoning tests are also likely to be specific to the sector applied for; meaning that applications for a role with the police will often include questions that refer to problems or scenarios that the police are likely to encounter.

Well known mechanical reasoning tests include:

Bennett Test of Mechanical Comprehension: This test is generally used for engineering and mechanical occupations, and measures the ability to comprehend how physical force affects mechanics.

Wiesen Test of Mechanical Aptitude: This is likely to be used in candidate selection for occupations that require the ability to operate and service tools and machinery; and measures this ability within its assessment.

Barron's Test of Mechanical Aptitude: Typically used in selection procedures for the military, this test assesses candidates based on subjects related to the abilities a person would need to succeed in this occupation.

Stenquist Test of Mechanical Aptitude: This test does not require experience in a particular area; it is based around questions in which the candidate has to pick one of four pictures that best fits with a picture they are previously shown.
