Answer 1

Concept:

The relationship between elastic modulus, bulk modulus and Poisson's ratio is given by

\(E=3K(1-2\mu)\)

The relationship between elastic modulus, modulus of rigidity and Poisson's ratio is given by

\(E=2G(1+\mu)\)

The relationship between elastic modulus, modulus of rigidity and bulk modulus is given by

\(E={9KG\over{G+3K}}\)

Calculations:

Given:

Poisson's ratio, μ = 0.5

E = 2G (1 + μ)

E= 2G × 1.5 = 3G
