Answer 1

Concept:

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

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

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

Hence, combining all these equations and solving it together we can get,

Calculation:

Given data;

E= 240 GPa

μ = 0.2

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

G= 100 GPa
