    Question

    For a particular material, if the modulus of elasticity is two times modulus of rigidity, then the value of Poisson's ratio will be

    A.

    1/2

    B.

    1/4

    C.

    1/8

    D.

    None of these

    Correct option is D

    Relation between E,G,μ:E=2G(1+μ)Substitute E=2G:2G=2G(1+μ)Divide both sides by 2G:1=1+μ μ=0\text{Relation between } E, G, \mu: \\[6pt]E = 2G(1+\mu) \\[12pt]\text{Substitute } E = 2G: \\[6pt]2G = 2G(1+\mu) \\[12pt]\text{Divide both sides by } 2G: \\[6pt]1 = 1 + \mu \\[12pt]\therefore \; \mu = 0​​
