A steel block of dimensions 0.5m×0.3m×0.1m is subjected to a shearing force of 5×104N. If the shear modulus of steel is
Shear modulus: G = Shear stressShear strain. Shear stress: Shear stress = FA, A = 0.5×0.3 = 0.15m2. Shear stress: 5×1040.15≈3.33×105N/m2. Shear strain: Shear strain = Shear stressG = 3.33×1058.4×1010≈3.96×10−6.
