Correct Answer - Option 2 : rubber
Explanation:
Poisson's ratio:
Poisson's ratio is the ratio of lateral strain to longitudinal strain. Mathematically is given by,
\(μ = -\frac{Lateral\ strain}{Longitudinal \ Strain}\)
A negative sign in the formula is to make the ratio positive.
| Material |
Poisson's Ratio (μ) |
| Gold |
0.44 |
| Magnesium |
0.35 |
| Copper |
0.33 |
| Rubber |
0.4999 |
| Steel |
0.30 |
| Concrete |
0.20 |
| iron |
0.21-0.29 |
| Wood |
0.18-0.43 |
The Poisson ratio is the property of the material.
