# Mechanical Reasoning Tests

• 10 tests |
• 80 questions

A mechanical reasoning tests are assessments, often used for technical positions, that measure how candidates apply mechanical principles to solve problems. Mechanical aptitude questions can include gears, electrical circuits, or levers. These tests include a series of images showing mechanical problems or scenarios.

## Free practice mechanical questions

It is really important to practise mechanical reasoning questions as much as possible before your assessment. Put simply, the more familiar you are with the format of the questions and the topics covered, the better you are likely to perform on the day.

Below we have provided a selection of three sample mechanical reasoning questions. Here you can find more free cognitive ability tests, including mechanical reasoning and spatial awareness.

### Mechanical practice question 1

How many revolutions per second is C turning?

• A) 5
• B) 10
• C) 20
• D) 40

### Mechanical practice question 2

Which magnets will repel each other?

• A) None of them
• B) All of them
• C) Pairs B and C
• D) Pairs A and D

### Mechanical practice question 3

How much force is required to lift the weight?

• A) 60kg
• B) 120kg
• C) 180kg
• D) 240kg

### Solutions

Question 1: If a cog with 5 teeth can do a full 40 revolutions in a second, a cog with four times as many teeth with take 4 times as long to do a full revolution. This means, it will do 4 times fewer revolutions. So the correct answer is 10.

Question 2: Opposite poles on magnets attract, the matching poles repel. So the correct answer is A and D.

Question 3: There are two sections of rope that are supporting the weight, meaning that we can divide the force needed to lift the weight between them 120/2 = 60kg.

What is the primary purpose of a fuse in an electrical circuit?

• To increase the circuit's power capacity
• To prevent overheating by breaking the circuit if the current is too high
• To store electrical energy for later use
• To convert electrical energy into mechanical force

If the pressure inside a container is increased, what is the effect on the temperature of the gas inside, assuming the volume remains constant?

• The temperature will increase.
• The temperature will decrease.
• The temperature will remain constant.
• The temperature will initially decrease then increase.

Which of the following best explains how a lever can be used to lift a heavy object?

• A lever increases the weight of the object.
• A lever reduces the effort needed by increasing the distance over which the force is applied.
• A lever changes the direction of the applied force.
• A lever decreases the gravitational pull on the object.

What magnitude of force needs to be applied to a 2-meter-long lever with a fulcrum at the 0.5-meter mark to lift a 100 kg weight at the short end?

• 200 N
• 400 N
• 800 N
• 1000 N

Which of the following statements is true if two gears are meshed together and one has twice the number of teeth as the other?

• The gear with more teeth will rotate twice as fast.
• The gear with fewer teeth will rotate twice as fast.
• Both gears will rotate at the same speed.
• It is impossible to determine the rotational speed without knowing the input force.

The tests were well suited to the job that I’ve applied for. They are easy to do and loads of them.

## Mechanical Reasoning Tests Tips

### 1Practice, practice, practice

Practicing example questions is the very best way to prepare for mechanical reasoning tests. By trying your hand at practice tests you will gain a much better understanding of the types of problems you are likely to face during the test. This will give you time to brush up on any gaps or weak spots in your understanding of the key topics and principles.

### 2Revise key mechanical principles and techniques

Make sure you have a thorough understanding of the main concepts covered in mechanical reasoning tests and are able to apply them to solve real problems. For each question, think carefully about which technique you need to apply.

### 3Recreate exam conditions

Try to practice in conditions similar to those in which you will be sitting your real mechanical reasoning test. Find a quiet environment with minimal distractions and make sure you stick to the time limit. This will keep you more focused and will make the real assessment less daunting.

### 4Try things out for yourself

As well as completing practice tests, you can improve your mechanical reasoning skills in a more practical way. Try taking mechanical equipment apart to gain a better understanding of how it works, look for opportunities to work with different tools and equipment, and refer to technical user manuals to increase your knowledge.

### 5Work quickly but accurately

Make sure you understand how many questions you will have to answer and how long you have to complete the test. These tests are designed to put you under pressure and you may have as little as 30 seconds to answer each question. But remember only a small minority will complete the test; it’s more important to focus on getting the answers right.

Make sure that you have understood what you are being asked to do, and double-check your calculations. Each question will only have one correct answer.

Find out as much as possible about the assessment before the test, such as which provider the recruiter is using and the format of the test. Employers typically provide this information to candidates on their careers website; if it’s not available, ask the HR department or other relevant point of contact.

### 8Be competitive

Try to measure your achievements against other users to make sure you stand out from the crowd. An average score might help you pass to the next stage, but may not be enough to bag you that job.

## How are mechanical reasoning tests scored?

Your score will be formed from the number of questions you answer correctly in the test. This will most likely be compared to a ‘normative group’ to define how you performed in relation to others. It is worth noting that most tests only have a completion rate of about five per cent. The majority of candidates will not get through all the questions, so it is more important to provide accurate answers than to focus on completing the test. Only the questions you answer correctly will count towards your score.

## Which employers use mechanical reasoning tests?

Mechanical reasoning tests are highly specialised assessments, which you will only encounter for positions that require mechanics or electronic knowledge and skills. These include engineering and technical positions, emergency services and roles within the military. Mercedes Benz, Shell and Amazon are some of the major employers that use mechanical reasoning tests in their application processes.

## What is basic mechanical knowledge?

Basic mechanical knowledge involves the ability to understand how mechanical equipment and tools work, and to apply that knowledge in practical situations. Those with basic mechanical knowledge are able to recognise and work with a number of key principles, such as force and movement, hydraulics, velocity and simple electrical circuits, among others.

## What are examples of mechanical skills?

Mechanical skills might include repairing mechanical equipment, performing tests and analysing the results, carrying out equipment and system calculations, troubleshooting equipment, analysing problems and identifying solutions, and designing devices and components.

## Where can I practice mechanical reasoning tests?

The best way to excel in mechanical reasoning tests is through consistent practice; this website is a good place to start. Here you can find the most widely used mechanical reasoning tests along with guides, tips, and practice questions set under test conditions.

## What are mechanical reasoning tests used for?

Mechanical reasoning tests are used to evaluate a person’s ability to use the concepts of mechanics or electronics to solve problems. They are predominantly used during the selection process for engineering or technology-related roles.
