Distinguish between Young's modulus,bulk modulus and the modulus of rigidity.

For most materials the Youngs modulus is n times the modulus of rigidity, where n is

If the Young's modulus of the material is 3 times its modulus of rigidity, then its volume elasticity will be

For the different materials it is given that Y_(1) gt Y_(2) and B_(1) lt B_(2) . Here, Y is Young's modulus of elasticity and B, the Bulk modulus of elasticity. Then we can conclude that

Young's modulus of a wire depends on

Modulus of rigidity of a liquid

The dimensional formula for modulus of rigidity is

Young's modulus of elasticity is the ratio of

For aluminium the bulk modulus and modulus of rigidity are 7.5xx10^(10) Nm^(-2) . Find the velocity of longitudinal waves in the medium. Density of aluminium is 2.7xx10^(3) kgm^(3) .

isobaric modulus of elasticity is

Young's modulus for a perfectly rigid body is
