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

Modulus of rigidity of a liquid

For a given material, the Young\'s modulus is 2.4 times that of rigidity modulus. Its Poisson\'s ratio is

Minimum and maximum values of Poisson\'s ratio for a metal lies between

The reason for the change in shape of a regular body is

The lower surface of a cube is fixed. On its upper surface, force is applied at an angle of 30° from its surface. The change will be of the type

The upper end of a wire of radius 4 mm and length 100 cm is clamped and its other end is twisted through an angle of 30°. Then, angle of shear is

A 2 m long rod of radius 1 cm which is fixed from one end is given a twist of 0.8 radians. The shear strain developed will be

A rod of length land radius r is joined to a rod of length 1/2 and radius r/2 of same material. The free end of small rod is fixed to a rigid base and the free end of larger rod is given a twist of 0°, the twist angle at the joint will be

Shearing stress causes change in
