Chapter 10, Problem 86A

To determine

The position of hands on the clay hammer handle.

Explanation of Solution

Introduction:

Torque is a type of force which is responsible for the rotation of object about an axis.

The force can increase or decrease the velocity of an object and similarly torque can increase or decrease the angular velocity of an object. Therefore, torque is equivalent to force. The axis about which the body rotates is called axis of rotation.

The formula of torque is,

  $\tau =F\times d$

Where, $\tau$ = torque

  $F$ = force

  $d$ = distance from an axis

When force is constant, then torque is directly related to the distance between the point where force is applied andthe axis of rotation.

The linear force applied by person is transferred to an object with help of hammer in the form of torque.

The formula of toque is, $\tau =F\times d$ .

The torque is directly to distance between the point where force is applied and axis of rotation,if applied force constant.

To impart a large amount of force on the nail, the distance of hands should be as large as possible.
