Example Questions of a Mechanical Reasoning Test

Let's delve into some examples with mechanical reasoning practice test questions:


Question 1: Forces and Motion

A car is moving uphill. Identify the force acting against its motion.

a) Friction
b) Gravity
c) Inertia
d) Tension

The correct answer is: a) Friction

In this scenario, friction opposes the motion of the car. When a vehicle moves uphill, friction acts in the opposite direction to the motion, making it harder for the car to climb.

Question 2: Pressure and Fluids

In a hydraulic system, if the area of the smaller piston is half that of the larger piston, and a force of 200 Newtons is applied to the smaller piston, what force will be exerted by the larger piston?

a) 100 Newtons
b) 200 Newtons
c) 400 Newtons
d) 800 Newtons

The correct answer is: c) 400 Newtons

The force in a hydraulic system is transmitted equally to all parts. Since the larger piston has twice the area, it will experience twice the force. Therefore, 200 Newtons on the smaller piston results in 400 Newtons on the larger piston.

Question 3: Temperature and Heat Transfer

If a metal rod is heated at one end, which end will reach a higher temperature first?

a) The heated end
b) The unheated end
c) Both ends simultaneously
d) It depends on the type of metal

The correct answer is: a) The heated end

Heat transfers along the metal rod from the heated end to the unheated end. Therefore, the heated end will first reach a higher temperature as the particles gain energy and transfer it through the metal.

Question 4: Gears and Mechanical Systems

In a gear system, if Gear A rotates clockwise, what direction will Gear B rotate?

a) Clockwise
b) Counter clockwise
c) It won't rotate
d) Depends on the size of the gears

The correct answer is: b) Counter clockwise

Gears in contact rotate in opposite directions. If Gear A rotates clockwise, Gear B, in contact with A, will rotate counterclockwise.

Question 5: Mechanical Comprehension

An object is in motion. According to Newton's first law of motion, what can be inferred?

a) The object is accelerating
b) The object is at rest
c) The object experiences a net force
d) The object will stop soon

The correct answer is: c) The object experiences a net force

Newton's first law states that an object in motion will remain in motion unless acted upon by an external force. Therefore, the object is experiencing a net force to keep it in motion.
