MCQ
The value of Poisson's ratio lies between
- ✓-1 to $\frac{1}{2}$
- B$-\frac{3}{4}$ to $-\frac{1}{2}$
- C$-\frac{1}{2}$ to 1
- D1 to 2
✓
Answer
Correct option: A.
-1 to $\frac{1}{2}$
(a) $Y=3 K(1-2 \sigma), Y=2 \eta(1+\sigma)$For $Y=0$, we get $1-2 \sigma=0$, also $1+\sigma=0$$\Rightarrow \sigma$ lies between $\frac{1}{2}$ and -1 .
