MCQ
For a given material, the Young's modulus is 2.4 times that of rigidity modulus. Its Poisson's ratio is
- A2.4
- B1.2
- C0.4
- ✓0.2
✓
Answer
Correct option: D.
0.2
(d)$\begin{aligned}& Y=2 \eta(1+\sigma) \\& 2.4 \eta=2 \eta(1+\sigma) \Rightarrow 1.2=1+\sigma \Rightarrow \sigma=0.2\end{aligned}$
