Question

Relation between three moduli of elasticity is given by

Answer 1

3 Types of Elastic Moduli. Young's modulus (E) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus.

Answer 2

Explanation:

Similarly the net change in dimension along the direction of Q is f = λQ - �P - �R and the net change in dimension along the direction of R is g = λR - �P - �Q. If only P acts and Q = R = 0 then it is a case of longitudinal stress. This is the relation between the three moduli of elasticity.
