Correct Answer - Option 4 : (a) - (c) - (b)
Explanation:
Poisson's ratio:
The ratio of lateral strain to the longitudinal strain is a constant for a given material. When the material is stressed within the elastic limit this ratio is called Poisson's ratio.
\(μ = \frac{{ - lateral\;strain}}{{longitudinal\;strain}}\)
In general, for engineering purpose value of Poisson's ratio vary from 0 to 0.5.
The value of μ for some important material is listed below;
Material |
Value of μ |
Cork |
0 |
Concrete |
0.1 to 0.2 |
Mild steel |
0.286 |
Cast iron |
0.23 to 0.27 |
Aluminum |
0.33 |
Glass |
0.05 to 0.1 |
Rubber |
0.5 |
