Question

A metal block of side 40 cm is subjected to a shearing force of 2000 N, and the upper surface displaces by 0.5 cm. What is the shear strain?

Options

• 0.0125

• 0.125

• 0.00125

• 1.25

Answer 1

0.0125

Explanation:

Shear strain θ = Δl/l = 0.005 m / 0.40 m = 0.0125. Shear strain is a dimensionless ratio.
