Question

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

Answer 1

Answer: (B)

0.004

Answer 2

$r \theta = L \phi \Rightarrow 10 ^ { - 2 } \times 0.8 = 2 \times \phi \Rightarrow \phi = 0.004$
