I'd wish to have had more time to learn
I regret not buying the SHL Assessment prep pack earlier. I only purchased it a night before the exam and failed on my first attempt because I couldn't absorb all the information in such a short amount of time. However, after having more time to review the material, I passed on my second attempt with a very high score of 94%. Therefore, I suggest to future clients to purchase this prep course at least 2-3 days prior to the exam.[...]Show Less

SHL Mechanical Comprehension Question Types

This Mechanical comprehension Test covers five essential topics in the field of mechanical engineering: Gears, Force and Torque, Fluid Mechanics, Tools, and Equipment. Each topic represents a fundamental aspect of mechanical comprehension principles that candidates are expected to comprehend and apply. Let’s look at these topics in detail and sample questions you can expect

Gears

Gears are essential elements in mechanical systems, responsible for power transmission and control of speed and torque. In the SHL Mechanical Comprehension Test, the topic of gears focuses on understanding the principles of gear systems, including gear types, ratios, and their applications in mechanical engineering. It is important to be familiar with gear terminology, gear engagement, and gear trains. Additionally, practical knowledge of gear applications in different industries, such as speed reduction, torque amplification, direction change, and synchronization, is crucial.

Sample Question

Question: The image shows two meshing gears, with the larger gear having 64 teeth and the smaller gear having 24 teeth. The larger gear is being turned at a constant speed. If the larger gear completes 30 revolutions, how many revolutions would the smaller gear complete?

SHL Mechanical Comprehension Sample Question 1

Options:
  • A:

    80 revolutions

  • B:

    90 revolutions

  • C:

    100 revolutions

  • D:

    120 revolutions

Correct Answer: A) 80 revolutions

Explanation:

The number of revolutions a gear makes is inversely proportional to the number of its teeth. This is because the larger gear with more teeth will move a smaller gear with fewer teeth more times. Therefore, in a gear system, if the larger gear (with 64 teeth) makes 30 revolutions, the smaller gear (with 24 teeth) will make (64/24)*30 = 80 revolutions.

Force & Torque

This topic explores the concepts of forces and torques in mechanical systems. You should have a solid understanding of calculating forces, interpreting torque, and analyzing their effects on mechanical components and systems. Key areas to focus on include:

Force Analysis: You need to be proficient in analyzing the forces acting on mechanical components, considering factors such as magnitude, direction, and point of application. This includes understanding the principles of static equilibrium and dynamic forces in relation to mechanical systems.

Torque Analysis: Mastery of torque analysis and calculations is essential, including understanding the relationship between force, distance from the axis of rotation, and the resulting torque. You should be able to calculate torques accurately using relevant equations.

Effects of Forces and Torques: You should know how force and torque affect the behavior of mechanical systems and tools. This includes knowledge of concepts such as rotational motion, angular acceleration, and the resulting effects on speed, stability, energy transfer within the system, etc.

Sample Question

Question: The image shows a pulley system being used to lift a heavy box. The rope is wound around multiple pulleys. Will the user require more or less force to lift the box compared to lifting it directly?

SHL Mechanical Comprehension Sample Question 2

Options:
  • A:

    More force.

  • B:

    Less force.

  • C:

    The same amount of force.

  • D:

    Not enough information to determine.

Correct Answer: B) Less force

Explanation: A pulley system reduces the amount of force required to lift an object by spreading the force over multiple lengths of rope. Therefore, the user will require less force to lift the box using the pulley system compared to lifting it directly.

Fluid Mechanics

The Fluid Mechanics section of the SHL Mechanical Comprehension Test emphasizes the principles and behavior of both liquids and gases. It is essential to have a deep understanding of crucial fluid properties such as density, viscosity, and pressure, as well as the ability to calculate pressures accurately. Practical application of fluid mechanics principles, including working with hydraulic systems, pumps, pipes, and fluid flow control devices, is necessary to successfully tackle the questions in this category.

Sample Question

Question: The image displays two pipes, one with a larger diameter (Pipe A) and one with a smaller diameter (Pipe B). If the same amount of water is flowing into both pipes, which pipe will have the higher fluid speed?

SHL Mechanical Comprehension Sample Question 3

Options:
  • A:

    Pipe A

  • B:

    Pipe B

  • C:

    Both will have the same fluid speed.

  • D:

    There is not enough information to determine.

Correct Answer: B) Pipe B

Explanation: According to the principle of continuity, which is derived from the conservation of mass, the speed of a fluid (in this case, water) increases as it moves through a pipe with a smaller cross-sectional area. Therefore, the water will move faster through Pipe B, which has a smaller diameter than Pipe A.

Tools

This section evaluates your knowledge and expertise in mechanical tools commonly used in engineering and manufacturing industries. It reckons your familiarity with tool functions, proper usage, and safety protocols. Questions may present visual representations of tools, requiring candidates to identify their names, purposes, or appropriate applications.

Sample Question

Question: The image shows a man using a crowbar to open a crate. He places the fulcrum closer to the crate. Will this make it easier or harder to open the crate?

SHL Mechanical Comprehension Sample Question 4

Options:
  • A:

    Easier

  • B:

    Harder

  • C:

    The difficulty remains the same

  • D:

    Not enough information to determine

Correct Answer: A) Easier

Explanation: The crowbar acts as a lever, and the force exerted by a lever is inversely proportional to the distance from the fulcrum to where the force is applied. So, by placing the fulcrum closer to the crate, the man will have to apply less force to open the crate.

Equipment

The Equipment category assesses candidates’ level of familiarity with various mechanical equipment typically found in industrial environments. Questions in this section cover a wide range of topics, including machine operation, adherence to safety protocols, and equipment maintenance. Candidates are expected to demonstrate their knowledge and understanding of operating procedures, safety measures, and best practices related to mechanical equipment commonly encountered in industrial settings.

Sample Question

Question: The image shows an industrial robot arm paused during operation due to an error. Which of the following actions should a technician do first?

SHL Mechanical Comprehension Sample Question 5

Options:
  • A:

    Attempt to manually move the robot arm.

  • B:

    Restart the control system to clear the error.

  • C:

    Report the issue and follow procedures.

  • D:

    Try to resolve the error themselves

Correct Answer: C) Report the issue and follow procedures

Explanation:

Standard operating procedures in industrial settings typically involve reporting any malfunctions or errors immediately to a supervisor or a responsible team. Attempting to resolve issues without proper procedure can potentially result in additional damage or safety risks.

Skills Required for Passing the SHL Mechanical Comprehension Test

A strong foundation in mechanical principles, the ability to solve problems, technical aptitude, attention to detail, effective time management, critical thinking, and familiarity with safety protocols are crucial for achieving a high score in the test.
