Question

If the young's modular of elasticity of a material is twice its modulus of rigidity, then the poisson's ratio of the material is

Answer 1

the answer is zero.
Explanation: the relation between poisson's ratio, modulus of elasticity and modulus of rigidity is
E= 2G(1+Mu)

where, Mu- poisson's ratio.
E- modulus of elasticity.
G- Modulus of rigidity.

Now according to the question, E= 2G

=> 2G =2G(1+Mu)
=> 1 = 1+Mu
=> Mu = 0.

Answer 2

Answer:

zero

Explanation:

E=2G(1+Mu) where Mu is poissons
