m = 1/0.25 = 4,
C = 125 * 4/2(4 + 1) = 50.
C = 125 * 4/2(4 + 1) = 50.

Young modulus(E)= 125GPa,
Poisson ratio(1/m)=(1/0.25)= 4.
Formula, Mod of rigidity(G)= (m.E)/{2(m+1)}= 50GPa.
Poisson ratio(1/m)=(1/0.25)= 4.
Formula, Mod of rigidity(G)= (m.E)/{2(m+1)}= 50GPa.

If the modulus of elasticity is 100 GPa and Poisson's ratio is 0.2 then the modulus of rigidity and bulk modulus respectively.

E = 2G(1+nue) Where nue = poisson ratio.
125 = 2G(1+.25).
125 = 2.5G.
G = 50 GPa.
125 = 2G(1+.25).
125 = 2.5G.
G = 50 GPa.
