Sample Mechanical Aptitude Questions and Answers
To give you a head start, here are a few sample questions commonly found in mechanical aptitude PDFs:
Question 1:
What is the mechanical advantage of a lever where the effort arm is 4 meters long and the load arm is 1 meter long?
Answer:
The mechanical advantage (MA) of a lever is the ratio of effort arm to load arm.
MA = Effort arm / Load arm = 4 / 1 = 4

Question 2:
In a gear train, if the driver gear has 20 teeth and the driven gear has 60 teeth, what is the gear ratio?
Answer:
Gear ratio = Number of teeth in driven gear / Number of teeth in driver gear = 60 / 20 = 3
This means the driven gear rotates at one-third the speed of the driver gear.

Question 3:
A boiler heats water at a rate of 2 kg per minute. If the specific heat capacity of water is 4.186 J/g°C and the water temperature increases by 10°C, how much heat energy is required?
Answer:
Total mass = 2 kg = 2000 g
Heat energy (Q) = mass × specific heat capacity × temperature change
Q = 2000 g × 4.186 J/g°C × 10°C = 83,720 Joules
