# Bennett Mechanical Comprehension Tests

• 10 tests
• 80 questions

The Bennett Mechanical Comprehension Test demonstrates your ability to understand mechanical concepts and apply them to solve problems. It has been used for more than 60 years in various forms as a screening and capability test for military, engineering and other technical roles.

## Free practice mechanical questions

As with all other aptitude tests, one of the most important things you can do to improve your score is to practice.

With the practice questions below, you will be able to see the layout and check that you are comfortable with the way you need to answer. Solutions follow beneath the questions.

### Mechanical practice question 1

What force is required to lift this weight?

• A) 30kg
• B) 50kg
• C) 100kg
• D) 150kg

### Mechanical practice question 2

If two cogs are turning together, one with 30 teeth and the other with 20, how many revolutions would the smaller cog have turned if the larger cog had rotated 15 times?

• A) 21
• B) 21.5
• C) 22
• D) 22.5

### Mechanical practice question 3

Which container is being represented in this graph as it is filled with water?

### Solutions

Question 1: There are 6 sections of rope supporting the weight, meaning we must divide the total weight by 6. 300 / 6 = 50kg (B).

Question 2: The smaller cog rotates 1.5 times quicker than the larger as there are 1.5 times more teeth on the latter cog. This means that is the cog with 30 teeth has rotated 15 times, the smaller cog will have turned 1.5 times more. So 15 x 1.5 = 22.5 (D).

Question 3: The steepest lines on the graph represent the thinnest part of the container, as this is the part of the container that would become fuller quicker. This graph represents a container that starts thin, gradually becomes wider and then becomes thin again at the top. The answer is B.

Within two hours of practice I have improved my score from 50% correct to 88%.

## Is the BMCT hard?

The structure and language of the Bennett Mechanical Comprehension Test is not designed to be difficult. In fact, it is aimed at a sixth-grade level. The difficulty of the BMCT comes from the application of this relatively basic knowledge to answer questions – and doing it quickly.

## What are basic mechanical skills?

Some of the basic principles that you might need to understand include: pulleys; force and movement (Newton’s three laws of motion, friction and gravity); fluids (hydraulics, the ideal gas law, Bernoulli’s principle); thermodynamics (heating, cooling, evaporation and condensation); electricity (Ohm’s Law, circuits); wheels (rotational and linear velocity, the relationship between wheel size and speed); gears (direction of rotation, gear ratio); acoustics (refraction, reflection, the Doppler effect, attenuation); optics (principles of light, reflection and sight).

## Where can I practice mechanical reasoning tests?

To get started, you can practice some free mechanical comprehension tests on our mechanical reasoning tests page.

## What are mechanical reasoning tests used for?

Mechanical reasoning tests are generally used to assess how well the test taker can apply mechanical principles to solve problems in a practical environment. As part of the recruitment process, these tests can show whether an applicant has a natural affinity for mechanics and would be successful in a role where this is needed.

## Bennett Mechanical Comprehension Tests Tips

The questions are usually not complicated, so take some time to read them thoroughly and it will help you to understand how best to answer.

### 2Use the graphics

Each question is accompanied with a graphic or image that demonstrates the mechanical law that is being assessed. The answer is in the image – you just need to apply the correct mechanical reasoning.

### 3Practice

It might seem obvious, but the best way to prepare and succeed in a mechanical reasoning test is to practice. Pearson has stated that those who practice regularly can increase their score by 4 points on average – and while that might not seem like much, it could be the difference between a pass and a fail.

### 4Be quick

With 55 questions to answer in just 25 minutes, there is not a lot of time to spend on each one. This means that you need to be able to answer quickly as well as accurately to be successful.

Unlike some other types of aptitude tests that require you to use only the information in front of you, the Bennett Mechanical Comprehension Test makes use of your prior knowledge and also your competence at physics and mechanics.

## Reviews of our Mechanical Reasoning tests

What our customers say about our Mechanical Reasoning tests

#### Seems fine

This is the first practice test I've done, but it seems alright. I wonder if it will show me how to figure out the answers? I’m not sure of one.

• South Africa

May 18, 2022

On the one answer originally, I had the right answer but still clicked on the wrong answer because I was scared of running out of time.

• United States of America

#### It's OK

The test is not very engaging to participate with the questions. It's a good test website, and overall test. However, it's not the best I've seen. Would, however, recommend to people.

#### Basic Understanding of Gears

I liked the variety of questions, the only downside was the few easy question such as which car color would overheat.

• Czechia

April 27, 2022

#### Basic physics

I like that you do not need to know any specific language to complete the test, as it's mostly pictographic.

#### Complicated

It's complicated but it's how the Ramsay test would be at a job site. Expect to be asked a lot of random things.

• India

#### It seems good for prep

In this test figures are very clear and easy to understand. Questions are also very relevant to the subject, though sometimes questions change but their figures remain unchanged.

April 13, 2022

#### Being able to analyze and think under pressure

I liked that this test was very different and each question threw you off. Being able to change the way you’re thinking and process the question is important

• United States of America

#### Great

I feel this is a wonderful test for determining a wide range of skills necessary for employers to properly gauge the aptitude of the potential employee. They are challenging questions, yet easy enough to understand what the questions are wanting to know.

#### Good intro questions

The cog question required some calculations. I would say an introductory portion shouldn't have any calculations, just simple statics/physics questions
