Simple Stress and Strain MCQ with answer and solution

Concept

E and G related by Poisson’s ratio

Formula

E = 2G(1 + ν)

Step-by-step solution

1. E/G = 2(1 + ν) = 2 × 1.2 = 2.4. 2. 2.4 = 12/5.

Explanation

For an isotropic material E = 2G(1 + ν). With ν = 0.2, E/G = 2.4 = 12/5.

Shortcut

E/G = 2(1 + ν).

Common mistake

Taking G/E.
