Question

A $2m$ long rod of radius $1cm$ which is fixed from one end is given a twist of $0.8$ radian. The shear strain developed will be

• A. $0.002$
• B. $0.004$
• C. $0.008$
• D. $0.016$

Answer 1

The correct option is B $0.004$

$\varphi =\frac{r\theta }{l}=\frac{1}{100}\times \frac{0.8}{2}=0.004$ radian
