What do Mechanical Comprehension Tests assess?
Mechanical Comprehension Tests measure a candidate’s existing knowledge of mechanical concepts, so is different from some of our other tests as it relies on existing understanding. Candidates are presented with questions related to pulleys, levers, cogs, springs, circuit boards, etc. and are required to determine what physical or mechanical principle applies to solve each question.
Typical roles that would use our mechanical comprehension test:
- Technical & Construction Roles - Engineers, Construction trades, Agricultural etc
- Emergency Services- Firefighters, Police, Ambulance etc
- Armed Forces Roles- Combat, Engineering, Logistics etc
Overview of the Mechanical Comprehension Test
Our mechanical comprehension test consists of a total of 32 items to answer in 20 minutes. There are 8 unique question sets, based on different mechanical concepts, and each comprise 4 individual questions.
All questions in the numerical reasoning test are multiple choice. The goal is to examine the diagram, use your understanding of basic mechanical concepts to perform a basic calculation (if necessary), and pick the correct answer from the selection.
Questions may take the form of the following:
- Weights on Scales: You are required to determine the amount of weight required to balance scales
- Completing a Circuit: You are required to predict which light flashes in circuit, depending on which switches are closed or opened
- Compressing Springs: You are required to determine the amount of force required to compress parallel and consecutive springs
- Rotating Wheels & Cogs: You are required to determine the speed and direction of rotation of connected wheels or cogs
- Weights on Pulleys: You are required to determine how much force is required to lift a weight on a pulley
- Water in Containers: You are required to determine how much the same volume of water fills different containers.

How to do well in your Mechanical Comprehension test
To do well in a mechanical comprehension test, it is good to implement the following tips:
1. Look at the diagram – Make sure you fully understand what the diagram is telling you prior to trying to answer the questions. This will save you time as each question set will be asking questions on the same graph.
2. Try not to over-complicate – These questions are not designed to be too challenging, so if you find yourself devising a complicated way of working out the answer, you are probably not using your time well. Remembering a single mechanical law and performing a simple calculation should suffice for answering most questions.
3. Do not be afraid to skip a question – This test is timed, so you may find that spending too long on a question you find tricky will significantly lower your eventual score. Feel free to skip ahead to questions you find easier and return to the challenging question at the end.
