Q. The value of Poisson’s ratio lies between
A) $- 1\ to\frac{1}{2}$
B) $- \frac{3}{4}\ to - \frac{1}{2}$
C) $- \frac{1}{2}\ to\ 1$
D) 1 to 2
Explanation
(a) $Y = 3K(1 - 2\sigma),\ Y = 2\eta(1 + \sigma)$
For $Y = 0$, we get $1 - 2\sigma = 0$, also $1 + \sigma = 0$
$\Rightarrow \sigma$ lies between $\frac{1}{2}$ and $- 1$
