What will be the approximate value of shear modulus of a material if the modulus of elasticity is 189.8 GN/mÂ² and its Poissons ratio is 0.30?

Civil Engineering : Strength of Materials - Quiz(MCQ)

73 GN/mÂ²

80 GN/mÂ²

93.3 GN/mÂ²

103.9 GN/mÂ²

Correct Answer : 73 GN/mÂ²

Explanation : The relationship between E, G, and μ is given by

E = 2G (1 + μ)
G = 189.8 / 2(1 + 0.30)
G = 73 GN/m²
