Elastic Modulie

Question

If Poisson's ratio $σ$ for a material is $\frac{1}{2},$ then the material is

Moderate

A

elastic fatigue
B

incompressible
C

compressible
D

None of these

Solution

We know that, compressibility, $C = \frac{1}{| B |}$
Also, $\frac{dV}{V} = (1 - 2 σ) \frac{dL}{L}$
Given, $σ = \frac{1}{2}$
$\frac{dV}{V} = 0$ , i.e. voIume is constant.
or $B = \infty$ , i.e. the material is incompressible.
