Did you know?
Mechanical Aptitude Tests typically include eight different question types: (1) forces, (2) levers, (3) pulleys, (4) gears, (5) springs, (6) simple electrical circuits, (7) hydraulics, and (8) tools. To progress in the hiring process, you’ll need to score 80% or higher. To achieve this, you’ll need to demonstrate mechanical comprehension, understand the workings of simple machines, and be familiar with basic physical forces.
Question Types Explained
Mechanical aptitude tests are generally timed multiple-choice tests. While each test is different, you can expect to have between 30-60 seconds per question. A Mechanical Aptitude Test is a multifaceted assessment tool, designed to measure your understanding and application of various mechanical concepts. The test is typically divided into several sections, each focusing on a different aspect of mechanical reasoning.
From basic physical forces to the use of common tools, these sections collectively provide a comprehensive evaluation of your mechanical aptitude. Understanding the types of questions you’ll encounter is the first step towards effective preparation. In this section, we’ll delve into the eight common question types found in a typical Mechanical Aptitude Test, explaining what each type assesses and the skills necessary to excel in each. Let’s explore these question types in more detail.
Basic Physical Forces
These questions test your understanding of fundamental physical principles such as gravity, friction, velocity, and heat. You might be asked to predict the trajectory of an object when certain forces are applied, or to identify the forces at work in a given scenario. To excel in this section, you need a good grasp of basic physics and the ability to apply these principles to real-world situations.
Basic Physical Forces Sample Question
Which weight will reach the ground first, if weight B is heavier than weight A?
(If at the same time, mark C.)
- A.
- B.
- C.
The correct answer is C – at the same time.
It can be seen that weight B is heavier than weight A, i.e. WB > WA. Now, weight is defined by Newton’s 2nd Law as:
Weight (W) = mass(m) * gravitational acceleration (g)
But for Earth, the gravitational acceleration is a constant i.e. 9.81m/s2. This shows that neglecting the effect of air resistance, the weight of a body does not change its downward acceleration due to gravity.
Even though weight A and B are different, according to Newton’s law, it does not change their accelerations towards the earth. This means that they will reach the ground at the same time.
Levers
This section presents diagrams of levers with weights placed at various points. You might be asked to calculate the force needed to balance the lever, or to predict the movement of the lever when a weight is added or removed. Success in this section requires an understanding of the principles of balance and equilibrium, as well as the ability to perform basic mathematical calculations.
Levers Sample Question
Two fixation points provide an accurate force to prevent the weights from breaking the poles. Which weight is heavier?
(If equal, mark C.)
- A.
- B.
- C.
The correct answer is B.
The given problem can be modeled as a beam balance with point O as the pivot. Summation of moments on O is zero since no rotation occurs. We denote the weights of load and counterweight as FL and FW and their moment arms as RL and RW respectively. Now, ΣM=0,
FW × RW – FL × RL = 0 or FL = RW/RL × FW
Since FW and RL are the same in both cases, and RW for B is greater than RW for A, hence load B must be heavier.
Pulleys
Questions in this section involve pulley systems. You might be asked to determine the force required to lift a weight using the pulley, or to identify the mechanical advantage of a given pulley system. To do well here, you need to understand how pulleys work and how they can make tasks easier by changing the direction of the force or multiplying the force applied.
Pulleys Sample Question
A stone is dragged in two different ways. In which method is it easier to drag the stone?
(If equal, mark C.)
- A.
- B.
- C.
The correct answer is A.
When the stone is pulled directly, the applied force (FB) is directly equal to the tension in the string. When a pulley is used, the tension is divided into two and the applied force (FB) is halved. This can be mathematically stated as:
FB = TB = FFriction and FA = TA = 0.5TB = 0.5FFriction
As shown in the figure below, the force resisting the movement is the friction force (FFriction). The pulley helps in dividing the required force into two parts and hence facilitates the process. Hence method A is easier for dragging the stone.
Gears
These questions involve diagrams of gear systems. You might be asked to determine the direction in which a gear will turn, or to calculate the speed of a gear based on the speeds of other gears in the system. This section requires an understanding of how gears interact with each other, as well as the ability to visualize the movement of interconnected parts.
Gears Sample Question
Three cogwheels mesh in a gear train. In which direction should gear Y rotate to have gear X rotate counterclockwise?
(If it cannot be determined, mark C.)
- A.
- B.
- C.
The correct answer is B.
As we know that the tangential velocity of two meshed gears always remains the same. However, their direction of rotation is always the opposite of each other. We can see that gear X meshes with another gear. We will call it the idler-gear. Gear Y meshes with the idler-gear as well.
In order to rotate the gear X counterclockwise, the idler-gear needs to be rotated clockwise. But since the idler-gear meshes with gear Y, it can only rotate if gear Y rotates counterclockwise. Hence gear Y should be rotated in direction B.
Springs
In this section, you’ll be presented with questions involving springs. You might be asked to calculate the force exerted by a compressed or stretched spring, or to predict the movement of a spring when a force is applied. To excel in this section, you need to understand Hooke’s law, which states that the force a spring exerts is proportional to its extension or compression.
Springs Sample Question
At which position of the torsion spring is the potential energy greater?
(If equal, mark C.)
- A.
- B.
- C.
The correct answer is B.
A torsional spring is an energy-storing element, which stores potential energy in the form of strain. Initially, the spring is at the normal extension, as shown by position A. When compressed, it compresses to position B. At this point, it has stored potential energy, which means that it will tend to regain its original position once the applied force is removed. Since the work done on the spring equals its change in potential energy, the potential energy of the spring increases when it is compressed from position A to position B after the work is done. Hence the potential energy of the torsional spring is greater at position B.
Simple Electrical Circuits
These questions test your understanding of basic electrical principles. You might be asked to identify the path of an electrical current, to determine the effect of a switch opening or closing, or to calculate the voltage or current in a simple circuit. Success in this section requires a basic understanding of electrical circuits, including concepts such as voltage, current, resistance, and the function of switches and loads.
Simple Electrical Circuits Sample Question
In the current structure, switch 1 is on and switch 2 is off. Which lamp will light up?
- Lamp 1
- Lamp 2
- Both/neither
The correct answer is C – neither.
It can be seen from the structure that the given circuit is short-circuited by a jumper wire connecting the two terminals, highlighted in the figure below. A short circuit occurs when two nodes having a finite potential difference are connected to each other without having any resistance between them.
According to Ohms’ Law: Current (I) = Potential Difference (V) / Resistance (R)
If resistance is near zero, then the amount of current flow will be very large. Since current always takes the path of least resistance, it will move through the jumper wire and will not pass through the bulbs. In this case, we do not need to consider the configuration of the switches.
Hydraulics
This section involves questions about the mechanical properties and uses of liquids. You might be asked to calculate the pressure exerted by a liquid in a container, or to predict the movement of a hydraulic system when a force is applied. To do well here, you need to understand Pascal’s law, which states that a change in pressure at any point in an enclosed fluid is transmitted equally throughout the fluid.
Hydraulics Sample Question
Water flows through the big pipe on the left and there is no air in the system. The cross-section area of each of the smaller pipe is exactly half that of the big pipe. What will be the velocity of the water flow in the smaller pipes?
- Greater than that of the big pipe
- Equal to that of the big pipe
- Less than that of the big pipe
The correct answer is B.
Since water is incompressible, we can safely assume that the density of water does not change from entering to leaving the system. Thus, we can conclude that the mass of water entering the big pipe will be equal to that leaving the smaller pipes i.e.:
Mass flow into the pipe (Δm1) = Mass flow out of the pipes (Δm2)
It is given that the cross-section area of each of the smaller pipe is exactly half that of the big pipe. This means that the cross-section area of both of the smaller pipes is equal to that of the big pipe.
In cases that the overall exit area is smaller than the entry area, the flow velocity in the exit area will be greater to compensate for this difference and balance the equation.
However, in our cases, there is no difference between the entry area and the exit area, therefore, no change in velocity is required to balance the equation.
Tools
In this section, you’ll be presented with images of various tools and asked to identify them and their uses. This section tests your familiarity with common tools and your understanding of their applications in mechanical tasks.
Tools Sample Question
What is this tool used for?
- To smooth surfaces by abrasion with sandpaper
- To grind metal and cut tile, stucco, and pavers, rout out mortar
- For light cutting, grinding, and cleaning tasks
- To flatten, reduce the thickness of a rough piece of lumber
The correct answer is A.
This power tool is a sander.

Results Scale and Interpretations
Understanding the scoring and interpretation of Mechanical Aptitude Test results is crucial for both test-takers and employers. The score report provides a comprehensive overview of a candidate’s mechanical aptitude and can be used to assess their suitability for roles that require these skills.
The score report of a Mechanical Aptitude Test typically includes the following components:
- Raw Score: This is the total number of questions that the test-taker answered correctly. It provides a straightforward measure of the test-taker’s performance.
- Percentile Ranking: This compares the test-taker’s performance to that of a norm group. For example, a percentile ranking of 70 means the test-taker performed better than 70% of the norm group.
- Sub-scores: Some tests provide sub-scores for different sections or types of questions. These can provide a more detailed view of the test-taker’s strengths and weaknesses.
- Score Range: This indicates the minimum and maximum possible scores on the test. The test-taker’s score can be compared to these ranges to assess their performance.
For instance, in the Ramsay Mechanical Aptitude Test (MAT), the test is scored based on the total number of correct answers, which is referred to as the raw score. This raw score is then compared to the performance of a norm group to determine the test-taker’s percentile ranking. The Ramsay MAT also provides T-Score equivalents for raw scores. The T-Score is a type of standardized score that adjusts the raw score based on the mean and standard deviation of the scores of the norm group.
For example, if a test-taker named John, who is 12 years old, gets a total of 26 questions right in Test I, his raw score is 26. By referring to the T-Score equivalents, we can see that a raw score of 26 is equivalent to a T-Score of 40. This means that John’s score is exactly at the -1 standard deviation position on the T-Scale. If we refer to the percentile ranks for the age of 12, we can see that a T-Score of 40 is equivalent to the 17th percentile rank. This means that John performed better than 17% of the 12-year-olds who took the test.
In conclusion, the score report of a Mechanical Aptitude Test provides a comprehensive overview of a candidate’s mechanical aptitude. By understanding the different components of the score report, test-takers can gain a better understanding of their performance, and employers can make more informed decisions about a candidate’s suitability for a role. For the most accurate information, I recommend checking the official test provider’s website or contacting them directly.
Mechanical Aptitude Test Scoring
This table provides a concise summary of the key components of a Mechanical Aptitude Test score report and how they are interpreted. This summary will serve as a quick reference guide for understanding your test results.

Question 1 of 7
Through which pipe will the water flow in greater pressure?
(If pressure will be the same, mark C.)
- A
- B
- C
The correct answer is C – the pressure will be the same.
The pressures in pipes A and B can be described by Bernoulli’s Theorem, which divides total pressure into three heads:
Total Pressure = Static Head + Dynamic Head + Elevation Head
The static head is the static pressure at the given point. The dynamic head, as the name suggests, is due to the velocity of the liquid and the elevation head is due to the height of the liquid.
In our case, the pressure at pipes A and B is due to the elevation head of water above them. This exerts equal pressure on both points A and B. When water shoots out from the pipes, its velocity is equal, in accordance with Toricelli’s theorem which gives the velocity of a jet as v = √2gh. h is equal for both A and B, so velocity is the same.
Due to the same velocity, the dynamic pressure head will also be the same. It is known that pressure is defined as, “force per unit area” i.e. P=F/A. So even though the jet force due to the flow rate will be greater for pipe B, the flow rate of a unit area will remain the same, and hence pressure for both A and B will be the same.
Question 2 of 7
A friend asked you to hand over an Allen wrench.
Which screw does he probably wish to tighten?
The correct answer is 
- Flat Head / Slotted / Straight wrench
- Phillips / Cross Head wrench
- Allen / Hex Head / Hex Key wrench
- Torx / Star Head wrench
- Robertson / Square-Head wrench
Question 3 of 7
Which part of the string has a higher strain on it?
(If neither, mark C.)
- A
- B
- C
The correct answer is C.
The string attached to a pulley is considered to be massless and “non-stretchable.” Therefore, it has an equal distribution of tension forces acting on it. This is due to Newton’s Third Law of equal and opposite reaction, acting on every point of the string. Also, consider the force balance on a small section of the string. As each small section of the string is in equilibrium, the tension (T) acting on it on both sides will be the same as shown in the figure.
If you extend this argument over the whole length of the string, you can conclude that the tension will remain the same on every part of the string, which means that neither part of the string has a higher strain rate than the other.
Question 4 of 7
At which position will the pendulum normally travel the fastest?
- A.
- B.
- C.
The correct answer is C.
The pendulum given above is a simple pendulum, having a bob of mass “m”, hanging from the pivot with a string of length “l”. let us assume that the pendulum is released from the horizontal position, which is the highest the pendulum can go.
As we know the potential energy of an object is greatest at its highest position, the pendulum will have the most potential energy at the horizontal position A. However, the speed of the pendulum at this point will be zero, which shows that the kinetic energy will also be zero.
According to the law of conservation of energy, the total energy at all points should remain the same.
Now, potential and kinetic energies are given as:
Potential energy = mass (m) * gravitational acc.(g) * height
Kinetic energy = mass (m) * velocity(v)2 / 2 [mv2/2]
At position A, the pendulum bob will have a greater height than in positions B or C, so its potential energy will be greater, but since the total energy is the same, the kinetic energy will be less than that of the other positions. This means that it will travel slower.
As the bob moves downwards, the potential energy will keep converting to kinetic energy and at position C, all the potential energy will be converted to kinetic energy. Hence the bob will move the fastest at position C.
Question 5 of 7
How many lamps will be lit if switch 1 is closed?
- 1
- 2
- 3
The correct answer is A – 1 lamp.
Current only flows between two points if there is a potential difference. In order to analyze the above circuit, define the nodes in the circuit. When switch 1 is closed, there are only three nodes—A, B, and C—in the circuit. In this case, lamps 1 and 2 are in the series; however, the potential difference across the series is zero since both end terminals are connected to node A. Therefore, lamps 1 and 3 will not light up. Lamp 2 is directly connected to the battery terminals A and C; therefore, lamp 2 will light up. This is why only one lamp will light up.
Question 6 of 7
Two people are balanced on a seesaw as in the top part of the image. If the left person jumps up, which of the scenarios, A or B, is likely to happen upon landing on the seesaw?
(If equally likely, mark C.)
- A.
- B.
- C.
The correct answer is A.
This is a case of a class 1 lever, where the people on the sides are loads and the fulcrum is in the middle. When the person on the left jumps on a balanced seesaw, the weight of the person on the right unbalances the seesaw and it falls to the right. When the person on the left lands on the seesaw, an effort is exerted due to weight, which lifts the seesaw from the right. However, it does not stop right in the middle due to the extra energy from the jump and keeps lifting the person on the right, as can be seen in scenario A.
Question 7 of 7
Which gear rotates fastest?
- A.
- B.
- C.
The correct answer is A.
The rotational velocities (ω) of directly meshed gears are inversely proportional to their number of teeth (N) as:
ω1/ω2 = N2/N1. This means that the greater the number of teeth is, the lower the speed is.
We have denoted the green gear as gear D. Now the number of teeth (N) of the gears is in the order: NB < NA < ND < NC.
Gear D directly meshes with gear A, so since gear A has fewer teeth than gear D, it rotates faster (ωA > ωD).
Since gear B and D are connected to the same shaft, they rotate at the same speed, i.e. ωB = ωD.
Gear B directly meshes with gear C, so since gear B has fewer teeth than gear C, it rotates faster (ωB > ωC).
Combining the conclusions above:
ωA > ωD = ωB > ωC
Gear A rotates the fastest and gear C rotates slowest.
