In terms of Poisson's ratio (μ) the ratio of Young's modulus (E) to Shear modulus (G) of elastic materials is
-
- 2(1 + μ)
- 2 (1– μ)
-
1 (1 + μ) 2 -
1 (1 - μ) 2
Correct Option: A
We know E = 2G[1 + v]
E/G = 2[1 + v].
18. Here, Px = Px = Px = – 15 × 106 Pa
(compression)
| Now, ex | = | = | = 3 × 10-5 | |||
| T2 | 2π | π |
where, m = Poisson’s ratio
ex = ey = ez = 3 × 10-5
ex + ey + ez = 9 × 10-5
∴ Change in volume = Total strain × Original = 90 m3
