Question

Define Young's modulus, Bulk modulus and Shear modulus.

Answer 1

Young's modulus
$= \frac{longitudnal \: stress}{longitudnal \: strain} \\ \\ bulk \: modulus = \frac{volume \: stress}{volume \: strain}$

Answer 2

Hey mate,

◆ Young's modulus-
It's the ratio of longitudinal stress to longitudinal strain within elastic limit.

Young's modulus = longitudinal stress / longitudinal strain

◆ Bulk modulus-
It's the ratio of volume stress to volume strain within elastic limit.

Bulk modulus = volume stress / volume strain

◆ Shear modulus -
It's the ratio of tangential stress to tangential strain within elastic limit.

Rigidity modulus = tangential stress / tangential strain
