Chapter 8, Problem 106A

To determine

To explain: The importance of a torque in automobile engines.

Explanation of Solution

Introduction:

Torque is a type of force which rotates the object. Torque increases angular acceleration of an object. It is rotational equivalent of linear force.

Automobile engine having rotating axel is connected to tire for producing the large force. The torque produced by the engine is the product of force applied on the edge of tire and the radius of a tire. So to accelerate an automobile at high rate, the engine should provide large torque on the tires. Thus, torque is an important quantity to measure, as large torque is needed to accelerate automobile at high rate.
