Mechanical Aptitude Tests

Mechanical Reasoning or Mechanical Aptitude Tests assess the test taker's ability to apply basic physical, mechanical, and technical principles in specific situations. These tests are meant specifically for examining the caliber of the test taker in extending fundamental concepts to practical application, rather than purely assessing only theoretical knowledge. These tests also examine the test taker's knowledge of the fundamentals underlying the operation, maintenance and repair of machinery and equipment. They are typically required in assessment centers or by the Human Resources (HR) departments of companies and industries that offer job roles such as engineer, technician, plumber, electrician, firefighter, and other blue-collar jobs.

Various names are used to describe Mechanical Aptitude Tests:

• Mechanical Aptitude Test
• Mechanical Reasoning Test
• Mechanical Psychometric Test
• Mechanical Comprehension Test

These names described the same tests and are interchangeable.

What Does a Mechanical Aptitude Test Look Like?

A Mechanical Aptitude Test is generally presented in the form of a multiple-choice questionnaire accompanied by simple illustrations, in color or black and white. The time limit for completing the test varies between test publishers and is usually between 20 and 30 minutes, but some tests may take two hours long. The number of questions also varies between 30 and 70 questions per test. The test can be taken online on a computer or on paper.

Where Is the Test Usually Taken?

The venue of the test is usually at the recruiting center of the company to which the candidate is applying. However, the use of online tests from remote locations that are convenient for the candidate have been increasing in the past few years and has become more commonplace since the beginning of the Covid-19 pandemic.

What Do Mechanical Aptitude Tests Evaluate?

Mechanical Comprehension Tests evaluate the candidate's competence and basic mechanical knowledge according to the following criteria:

• Mechanical reasoning skills
• Understanding and application of basic mechanical and physical concepts
• Understanding of basic electrical principles
• Spatial reasoning: visualizing shapes in three dimensions

What Are the Most Popular Topics in These Tests?

Mechanical comprehension tests contain questions on several popular topics that are fundamental to the subject. These include gears, gravity, pulleys, levers, thermodynamics (heat transfer), rotations, etc. Some of these topics are more commonly tested than others and should therefore be studied with special emphasis during your preparation and practice for the test to improve and succeed in your assessment.

Depending on the job and the test setter, the range of topics covered in any specific Mechanical Aptitude Test are usually restricted to concepts that are relevant for the job. However, if Mechanical Aptitude Test you wish to train on comprehensive mechanical aptitude practice tests that cover the whole range of topics and concepts, and read mechanical and electrical study guides, go to the following page.

Topics, Explanations, and Free Mechanical Sample Questions

The following section contains a full study guide with the basics of mechanics as well as free sample questions with explanations. Read it carefully and try to answer the questions before reading the solutions and explanations.

Mechanics

Newton's laws

Newton's three laws form the basis of the fundamentals of classical mechanics. These laws are taught in high school and are used to both formulate and solve problems in mechanics.

1. Newton's first law is known as the "principle of inertia". "Any body not subjected to forces retains its state of rest or rectilinear and uniform motion". Thus, ΣF=0, i.e., the set of forces to which the body is subjected is equal to 0.
2. Newton's second law is entitled "fundamental principle of dynamics". "In a frame of reference of inertia, the velocity of a material point varies proportionally to the sum of the external forces applied to it and inversely proportionally to its mass". Thus, ΣF=ma, i.e., the sum of the forces applied to an object is equal to its mass multiplied by its acceleration.
3. Newton's third law, the "principle of reciprocal action" or "action-reaction" is defined as "the actions of two bodies on each other are always equal and in opposite directions".

What Forces Can Be Applied to a Body?

The gravitational force of the object (mg): the mass of the object multiplied by gravity (9.8m/s²), which is equal to the weight (P).

Tension (T): tension exerted by a wire (e.g., pendulum).

The force of friction (F): The force of friction exists when two bodies are in contact. It always opposes motion. The friction force is not only contrary to the movement, but also essential to ensure contact between two surfaces (e.g., contact of tires on the road, braking).

Normal Reaction (N or R): Each body exerts a force on another body that is in contact with it. For example, if an object rests on a table, the table exerts a force on the object. This force is called the reaction of the support or normal reaction, it is always vertical to the contact surface.

In a Mechanical Aptitude Test, questions rarely deal directly with forces or Newton's laws. However, it is extremely important to keep them in mind because knowing these laws make it easier to simplify and understand exercises on mechanical forces, such as pulleys, levers, and springs.

Pulleys

The pulley is an elementary mechanical device. It consists of a wheel-shaped part used to transmit motion and is used with a rope or cable. Different kinds of pulleys appear in mechanical reasoning tests:

Fixed pulley

The tensions on both strands of the cable are identical. The fixed pulley simply allows the direction of applied force to be changed. If an object is lifted with a fixed pulley at constant speed (or at rest), then the tension is the same throughout the rope. A fixed pulley therefore does not change the norm of a force but only its direction and/or sense. To lift the body by a height h, the point of application of the force F must be moved by a distance x=h.

Movable Pulley

Movable pulleys move with the load to be lifted, which is supported by two strands of rope with equal tension T. A movable pulley thus changes the intensity of a force. To lift the load by a height h, the point of application of the force must be moved by x=2h.

Example of an Exercise With a Single Pulley

Which weight requires the least amount of force to move?

1. A
2. B
3. Both weights require the same force

Hoist

A hoist is a combination of several fixed and mobile pulleys. The mobile pulley reduces the force by half, the fixed pulley changes the direction and the sense of the force: F=P/2 Here again, the load is supported by 2 strands of rope x=2h.

Example of an Exercise With a Hoist

How much force is needed to move the weights?

1. 100 kg
2. 150 kg
3. 50 kg
4. 60 kg

Levers

A lever is, in general, a rigid body that can rotate around an axis and is subject to at least two forces called the "driving force" and the "resistance".

The lever has three parts:

• The driving force
• The fulcrum
• The load or resistance

There are three types of levers:

• The inter-support lever (1st Class Lever): Here, the fulcrum (support axis) is placed between the driving force (effort) and the resistance (load) (swing, toggle, scissors).
• The inter-resistance lever (2nd Class Lever): Here, the resistance is between the support axis and the driving force (wheelbarrow, nutcracker).
• The inter-motor lever (3rd Class Lever): Here, the driving force is between the support axis and the resistance (sugar tongs, pliers, tweezers).

Example of an Exercise With a Lever

How Much Force Is Needed to Lift the Weight?

1. 40 lbs
2. 50 lbs
3. 60 lbs
4. 70 lbs

Springs

A spring is a piece of wire or metal that can be extended or compressed by an external force and returns to its original length when the force is no longer applied.

There are two types of springs appearing in mechanical reasoning questions:

• Series assemblies
• Parallel assemblies

When the springs are arranged in series, each spring is subjected to the applied force. When the springs are arranged in parallel, the force is distributed equally among the springs.

Example of an Exercise With One Spring

A force of 5 kg compresses the springs in series by 10 cm. What is the total distance at which the springs in parallel are compressed?

1. 10 cm
2. 2.5 cm
3. 5 cm
4. 7.5 cm

Gravity

Essentially, gravity is the constant downward force that holds people and objects to the ground. This force is such that it resists any other force that attempts to lift bodies off the ground.

Speed of Fall Time

In matters of free fall of bodies, some essential fundamentals are as follows:

• The force of gravity exerted on every body is equal, regardless of its mass, size, or shape. Thus, two objects falling in free fall from the same height will always arrive at the same time, regardless of their differences in weight, mass, etc. A tennis ball and a bowling ball will hit the ground at the same time as long as both fall from the same height at the same time.
• The duration of the fall depends only on the initial height and does not depend on the mass of the body.
• Air friction is negligible in mechanical reasoning questions.

Example

Assuming that both balls fall in free fall from the same height, which ball will hit the ground first?

1. A
2. B
3. Both balls will hit the ground at the same time
4. The question does not give enough information

Pendulum

A simple pendulum is a device containing a mass suspended from an inextensible wire, which owes its oscillatory motion to gravity. In a simple pendulum, the mass oscillates only vertically, whereas a compound pendulum will have its mass oscillate horizontally and vertically.

Mechanical comprehension questions are usually about simple pendulums.

Good to Know

• The pendulum cannot exceed the initial height from which the mass is thrown.
• The longer the wire, the lower the swing speed.
• The equilibrium position is the position vertical to the axis.

Example

If the two masses shown are not in motion, which situation is the most unlikely?

1. La situation A
2. La situation B
3. Both situations are equally likely.
4. Both situations are equally unlikely.

Throwing a Ball

When a ball or any other projectile is thrown non-horizontally, the velocity vector forms an angle alpha with the x-axis. The motion forms a parabola. The ball then changes its trajectory and heads towards the ground.

Good to Know

• When the ball reaches its maximum height, i.e., the top of the parabola, the velocity on the Y-axis is zero; the ball only has a velocity on the X-axis.
• For equal velocity, the maximum range for a shot angle is always 45 degrees.
• For an equal velocity, complementary shooting angles have the same range (e.g., 30 degrees and 60 degrees).
• For the same value of alpha angle, the greater the velocity, the greater the range.

In a Mechanical Comprehension Test, it is rare to come across questions that deal directly with bullet throws. However, it is important to understand the basics of this topic, which can help in solving other questions.

Inclined Plane

An inclined plane is a flat, sloping surface (i.e., with one side higher than the other), which allows objects to be moved between different levels (e.g., ramps, slides, or mountainsides). Inclined plane questions usually involve angle of inclination, weight and height, and the effect of gravity on bodies.

Good to Know

• The steeper the plane, the greater the necessary force used to raise the object. This is due to gravity which always pulls bodies downward.
• Loads moving down an inclined plane will move faster and longer than on a flat horizontal surface.
• The steeper the plane, i.e., the greater the angle of inclination, the greater the speed of a ball dropped from the top of the plane.
• Friction is created when a surface and a body meet. This resistance makes the movement more complicated, whether down or up the plane.

Example

Assuming the boxes are of equal weight and made of the same material, which box will slide more easily down its ramp?

1. Box A
2. Box B
3. Both boxes
4. Neither of the two boxes

Rotations

Gears

Questions about gears appear frequently in mechanical reasoning tests. A system of gears forms a gear that transmits rotational motion and is connected to a rotating shaft that is driven by a power source. These gears appear in many mechanisms such as watches and gearboxes.

There are two types of rotation:

Rotation in the same direction: in this gear, the wheels are connected by a belt and rotate in the same direction, for example - in a bicycle.

Reverse rotation: in this gear, the wheels are in contact with each other and rotate in opposite directions, for example - in a clock.

Good to Know

• When gears are of the same size and have the same number of teeth, they will rotate at an equal speed. If the number of teeth is unequal, then the gear with fewer teeth will rotate faster.
• A gear with small wheels turning at the same speed as a gear with large wheels will make more turns in the same amount of time.
• If a gear has an odd number of wheels, then the last wheel will always turn in the same direction as the first.

Example

If bar Y moves to the left at a constant speed, how does bar X move?

1. To the left, faster
2. To the right, at the same speed
3. To the left, more slowly
4. To the left, at the same speed
5. To the right, more slowly

Winch

A winch is a mechanical device that allows to control the winding of a cable in order to carry or pull a load. The best-known example is the system for lifting a bucket in a well. The crank allows the mass to be lifted more easily.

Good to Know

• The longer the crank arm, the lesser the effort that is required to lift the object.
• The smaller the diameter of the cylinder, the lesser the effort that is required to lift the object.

Example

With Which Winch Is the Load More Complicated to Lift?

1. A
2. Both are equal
3. B

Speed of Rotation

If two wheels connected by a belt are the same size, they will also rotate at the same speed. When the two wheels are unequal in size, then it is necessary to calculate the ratio between the two wheels to determine their speed.

Size of B = Number of turns of A x Size of A.

Example

Which wheel completes the most revolutions per minute?

1. Wheel A
2. Wheel B
3. Wheel C
4. The wheels make an equal number of turns per minute

Direction of Rotation

If the belt is straight, both wheels rotate in the same direction.

If the belt is crossed, the two wheels turn in opposite directions.

Example

If wheel A turns clockwise, wheel B turns:

1. Clockwise
2. Counterclockwise
3. Impossible to know

Electricity

An electric circuit is a circuit made up of conductive elements linked together. The circuit is composed of:

1. A generator of electricity (battery or electrical outlet) with a positive and a negative pole.
2. Electricity conducting wires connected to the two poles of the generator.
3. An electrical device connected to the wires.
4. A switch to control the circuit.

Nomenclature

When the switch is open, the current does not flow and the circuit is said to be open. When the switch is closed, the current flows and the circuit is said to be closed.

Parallel Circuits

Branch circuit or parallel circuit: when an electric circuit contains several loops connected to the same generator.

Example

How many switches must be closed in order for a bulb to be lit?

1. 1
2. 2
3. 3
4. 4

Series Circuits

A series circuit is a circuit in which the various components are placed one after the other, offering only one possible path for the current.

Example

How many bulbs light on when the switch is closed?

Short Circuit

In the case of a short circuit, the circuit creates a shortcut, that is, it creates a path without a bulb, through an intermediate wire. Thus, the electricity flows through the circuit without the bulb rather than through the path with the bulb and, when the circuit is closed, the bulb goes out.

Magnetism

A magnet is a material that naturally develops a magnetic field and is able to attract certain materials such as iron, nickel, cobalt, and chromium. A magnet has a north and a south pole. Poles of the same nature repel each other, those of different natures attract each other. Magnets are therefore magnetic dipoles whose poles are inseparable.

Example

Which of these pairs of magnets attract each other in situations A and B?

Voltage

The electric voltage is the flow of the electric field along a circuit measured in volts by a voltmeter. It is noted U at the terminals of a dipole. When connecting batteries, the current flows only when the opposite poles of batteries in series or in parallel follow each other.

Example

Two batteries each supplying 1.5 V of electricity are connected. In the following two illustrations, which of these connections gives 3 V, figure 1 or figure 2?

1. Figure 1
2. Figure 2
3. Both figures
4. Neither of the two figures

Tools

In Mechanical Competency Tests, there are often questions about different tools, such as hammers, screws, etc. These questions may include tool identification, tool usage, and a comparison of different tools.

Tool Identification

Tool knowledge questions assess the candidate's ability to identify and/or determine the uses of common types of tools (hammers, wrenches, pliers, etc.). Becoming familiar with a wide range of tools is the best preparation for answering this type of question.

Example

What is the name of the following tool?

1. Mallet
2. Hammer
3. Sledgehammer
4. Pliers

Uses of the Tools

Example

Which tool or combination of tools is most useful for general woodworking?

1. Voltmeter
2. Hacksaw
3. Wood chisel
4. Flat chisel
5. Planer
6. Glass cutter
7. Wood saw
8. Soldering station
9. Welding machine

1. 4 and 2
2. 3, 5 and 7
3. 2, 4 and 6
4. 4 and 7
5. 3 and 6

Tool Comparison

Which tool is best for tightening and loosening nuts?

Tool A

 Tool B

1. Tool A
2. Tool B
3. Neither tool
4. Both tools

Fault Checking/Fault Diagnosis

Fault diagnosis questions are used for the selection of technical personnel who must be able to find and repair faults in electronic and mechanical systems. Indeed, with the sophistication of modern equipment and machinery of all types, it becomes essential that a potential candidate is able to address errors occurring in these devices in a logical manner.

Example

Which switch indicates an error?

1. A
2. B
3. C
4. D
5. E

Tips and Tricks

• In order to improve your mechanical aptitude,learn how the fundamentals of classical mechanics work in real situations. Work with tools and mechanical equipment, try to fix and repair different objects, build new objects using technical user manuals. You can also look at YouTube explainer videos talking about mechanical principles and tools.
• Try to learn and understand the different basic physical and mechanical (and electrical) principles and learn the key formulas by heart. It is true that most of the questions won't ask you to use those formulas, but they will test your understanding of the mechanical principles.
• Don't aim to answer a question too quickly but also don't answer it too slowly. Answering too quickly could cause you to mark erroneous answers that you could have avoided if you read the question carefully and with focus. Also consider the fact that some of the questions can be quite tricky which require understanding the structure of the question more than the principle being tested. The goal of these tests is to differentiate between candidates who understand the logic behind the principles and those who don't. On the other hand, answering too slowly could cause you to exceed the time limit set for the test. It is therefore important that you check in advance the number of questions your assessment is composed of as well as its total time duration, so that you know how much time on average is available for answering each question. This way you can manage your own time.
• Try to precisely identify the mechanical principle behind each question, so that you can recall all the information needed to answer the question with ease.
• Preparation is key. Extensive practice will improve familiarity with concepts and question types allowing you to understand the logic behind the fundamental principles and their practical application in aptitude test questions and make it easier for you to answer them. Check which mechanical assessment you must pass and prepare for it specifically. You can find complete and comprehensive preparation material for each of the Mechanical Aptitude Tests here.
