Question

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

• A. 0.001 radians
• B. 0.004 radians
• C. 0.002 radians
• D. 0.04 radians

Answer 1

The correct option is B 0.004 radians

Angle of shear is $\varphi =r\theta /L={10}^{-2}\times 0.8/2=0.004radians$
The correct option is (b)
