Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

The steering wheel of a car has a radius of 0.20 m, and the steering wheel of a truck has a radius of 0.30 m. The same force is applied in
the same direction to each steering wheel. What is the ratio of the torque produced by this force in the truck to the torque produced in
the car?
