Question

if stress is numerically equal to twice that of young's modulus the elongation will be

Answer 1

Given :

Stress on the body = Y

To Find :

The elongation of the body = ?

Solution :

• Young’s modulus is the ratio of stress to strain produced in the body

        $Youngs\:modulus = \frac{Stress}{Strain}$

• By substituting the values in the above equation, we get

        $Y=\frac{Y}{strain}$

        $Strain =1$

        $\frac{\Delta l}{l}=1$

        $\Delta l = l$

The strain produced in the body is equal to the original length of the body
