Mechanical reasoning test, or mechanical comprehension test, are commonly administered for engineering or technical positions. The mechanical reasoning aptitude test assesses your abilities when it comes to applying mechanical concepts and principles to solve problems. Mechanical comprehension tests include a set of mechanical problems that must be solved within a timed limit. The mechanical reasoning test has been designed so that roughly 1% to 5% of the population can correctly answer all the test questions within the time limit. Each questions of the mechanical comprehension test consists of a mechanical scenario possibly including acceleration, gravity, friction, pressure, moments, kinetic and potential energy, work and power, etc. Around 30 seconds per question should be spent on the mechanical reasoning test. The position you are applying to is a good indication of the difficulty of the mechanical reasoning test. For example, if it’s a managerial engineering position the test will be more difficult to correctly complete that if it’s an entry-level role.

JobTestPrep's online practice pack contains four complete, timed practice tests, each comprised of over 20 questions. Our pack also comes with score reports and detailed answer explanations to help you track your progress. Prepare for your mechanical reasoning exam and apply with confidence.

Mechanical Comprehension Test Preparation

The most effective way to prepare for your mechanical aptitude test is by developing simple factors to solving test problems such as the proper solving techniques and frameworks. Additionally, preparation helps the candidate’s mind recognise past questions, many of the questions you will encounter during the test will have a similar format to the free mechanical reasoning test you see below. Therefore, if a candidate recognises the question then they can solve it much quicker due to previous experience. Practising questions is definitely the best way to increase confidence and prepare for your mechanical comprehension test.

Sample Question 1

On which pole does the weight press harder?

  1. #1
  2. #2
  3. The weight presses equally on both poles

The rectangle pivots about the point of contact with the floor. The farther the pole is from the pivot point, the less force it needs to apply to achieve the same torque (the torque needed to keep the rectangle static). Thus Pole 2, the pole farther away from the point of contact with the floor, applies less force on the rectangle. This is essentially the Law of the Lever.

According to Newton's 3rd Law, the rectangle applies less force on Pole 2 as well.

Therefore, the correct answer is 1.

Sample Question 2

What would be the current flowing through point X if another identical power source were to be added in parallel to the circuit?

  1. Twice as strong
  2. Half as strong
  3. There is no difference

Observe how the extra power source was set up: both the positive and negative terminals are connected. Therefore, the same electric potential is kept at each end. In other words, the voltage remains the same. Since the resistors have not been modified, the resistance remains the same as well. Finally, according to Ohm's law (V=IR), the current remains the same.

Trivia: Adding a cell or battery in parallel is usually devised as a form of electrical backup to a circuit, not as a means to change the voltage.

Therefore, the correct answer is 3.
