Wiesen Test of Mechanical Aptitude (WTMA) – 2024 Guide

Jan 24, 2024

What Is the Wiesen Test of Mechanical Aptitude?

The Weisen Test of Mechanical Aptitude is a pre-employment test used by employers to evaluate individuals' mechanical reasoning ability. 

The test aims to determine whether an individual has the skills needed to maintain, repair, and use mechanical equipment safely and efficiently. To do this, the test evaluates individuals' understanding and practical application of various laws of motion and mechanical principles.

Candidates do not need to have prior mechanical knowledge. They must be able to use their understanding of mechanical principles and apply these concepts to questions using everyday objects.

The Wiesen Test Format

The Wiesen test comprises 60 multiple-choice questions that candidates must answer within a 30-minute time limit.

The test focuses on six main topics, some of which are further broken down into sub-topics, such as those detailed below:


The Motion of Objects

This section covers how objects move or behave under the influence of forces.

Questions related to the motion of objects in a mechanical reasoning assessment might cover topics such as:

  • Force and Motion Understanding how forces act and influence the motion of objects
  • Acceleration and Deceleration how objects accelerate or decelerate under the influence of different forces
  • Friction Understanding how friction affects the motion of objects on surfaces
  • Gravity – How gravity influences the motion of objects
  • Inertia – How inertia relates to the motion of objects
  • Momentum – Understanding how the momentum of an object is affected by its mass and velocity
  • Simple Machines Understanding the basic principles of simple machines and how they affect the motion of objects


Concepts of Machinery

This section focuses on an individual’s understanding of the principles and components related to machinery and mechanical systems. Some topics include:

  • Mechanical Components Understanding the basic components of machinery, such as gears, pulleys and levers, and how they function
  • Force and Motion Understanding how forces impact machinery and, in a mechanical system, how motion is generated or controlled
  • Power and Energy Understanding the concepts of power and energy in the context of machinery, including calculations related to work, power, and energy transfer
  • Fluid Mechanics Basic understanding of how fluids, such as liquids and gases, interact with machinery



This section refers to the principles and properties associated with magnetic fields and the behavior of magnetic materials.

This can include:

  • Magnetic Fields Understanding the concept of magnetic fields and how magnets produce them. Knowing the properties of magnetic field lines and how they interact with each other
  • Magnetic Force Understanding the force of attraction or repulsion between magnets
  • Magnetic Poles Understanding the concept of like poles repelling and opposite poles attracting
  • Magnetic Induction  Knowing how a magnetic field can induce magnetism in nearby materials


The test is formatted within the topics, so some topics are tested in greater depth than others. These topics include velocity (acceleration and gravity), torque, and force.

The test questions are presented in either graphic or text format and include multiple-choice answers.

Candidates must use their knowledge of the topics listed above to select which Wiesen technical assessment answers they believe are correct. 

Here are some examples of the types of questions you may get asked when taking the Wiesen Test of Mechanical Aptitude. 


Wiesen Test Example Questions


The two boats above carry the same cargo with the same weight. In a strong gust of wind, which of the boats would be the most affected?

a) Boat 1
b) Boat 2
c) Both boats will be affected equally

The correct answer is: a) Boat 1

In a strong gust of wind, Boat 1, with the taller and narrower sail, would likely be more affected compared to Boat 2. The taller sail of Boat 1 presents a larger vertical surface area to the wind, making it more susceptible to being pushed or tilted by the wind. This can significantly impact the boat's stability and manoeuvrability.


If dropped, which ball will hit the ground first?

a) Bowling Ball
b) Tennis ball
c) Both balls will reach the ground at the same time

The correct answer is: c) 

This outcome is explained by the principle of free fall, which states that in the absence of air resistance, all objects fall at the same rate regardless of their mass. This principle was famously demonstrated by Galileo at the Leaning Tower of Pisa. According to this principle, a bowling ball and a tennis ball, if dropped from the same height and under similar conditions (i.e., negligible air resistance), will hit the ground simultaneously.

In reality, air resistance can have a small effect, especially on objects with large surface areas relative to their mass, like a feather. However, for objects like a bowling ball and a tennis ball, the difference caused by air resistance is minimal, and in an idealized scenario (like in a vacuum), they would indeed hit the ground at the same time.

3. What does the resistor do in an electrical circuit in series consisting of a battery, a resistor, and a wire?

a) Limits the flow of the electric current
b) Amplifies the flow of the electric current
c) Neither of the above

The correct answer is: a)

In an electrical circuit, a resistor is a component that serves to resist the flow of electricity, thereby reducing the current that passes through it. The primary function of a resistor in a series circuit, which consists of a battery, a resistor, and a wire, is to limit or control the amount of electric current flowing in the circuit.

4. A parcel is placed on a flat table. An individual pushes the parcel to move it. If the force used to move the parcel is greater than the force of friction between the parcel and the surface, what impact will this have on the parcel's motion?

a) The parcel will move with constant velocity
b) The velocity of the parcel will increase
c) The parcel won’t move

The correct answer is: b) 

This outcome can be understood through Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass, often expressed as , where ' is the net force, ' is the mass, and ' is the acceleration.


How Is the WTMA Scored?

The Wiesen Test of Mechanical Aptitude gives a candidate two scores: a raw score and a percentile score. 

The raw score represents the number of questions a candidate answered correctly.

The percentile score, also known as a comparison score, represents how well a candidate did compared to the other test takers in a given group. This group is called the norm group and differs depending on the type of role or organization an individual is applying for. 

Many positions require candidates to attain 80% on the Wiesen Test of Mechanical Aptitude. Some junior roles may have a lower passing score; this is organization-dependent. 

Incorrect answers on the Wiesen assessment are not penalized; marks are given for correct answers. When taking the Wiesen test, candidates should focus on attaining their highest score.

Answer as many of the 60 questions as possible.

If you are stuck on an answer, either mark your best choice or move on to the next question. If you have time, you can return to any questions you are struggling with.
