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

A

$0.002$

B

$0.004$

C

$0.008$

D

$0.016$

(AIIMS-2019)

Solution

The shear strain generated in the rod given as,

$r \theta=L \phi$

$10^{-2} \times 0.8=2 \times \phi$

$\phi=0.004$
