Here, E = 2G(1+v)

E = 2G(1+μ).
Given E = 2G.
2G = 2G(1+μ).
2G/2G = (1+μ).
1 = 1+μ.
1-1 = μ.
μ = 0.
Where E = modulus of elasticity.
G = modulus of rigidity.
μ = Poisson ratio.
Given E = 2G.
2G = 2G(1+μ).
2G/2G = (1+μ).
1 = 1+μ.
1-1 = μ.
μ = 0.
Where E = modulus of elasticity.
G = modulus of rigidity.
