Bulk modulus of a perfectly rigid body is

Breaking stress for a wire of unit cross–sectional area is called its

For a given material, the young’s modulus is 2.4 times that of modulus of rigidity. Its poisson’s ratio is

A wire can be broken by applying a load of 20kg wt. The force required to break the wire of twice the diameter is

The following four wires are made of the same material. Which of these will have the largest extension when the same tension is applied

A wire of length L and radius r is fixed at one end and force F applied to the other end produces an extension y. The extension produced in another wire of the same material of length 2L and radius 2r by a force 2F is

Two wires A and B are made of same material.The wire A has a length l and diameter r while the wire B has a length 2l and diameter r/2. If the two wires are stretched by the same force, the elongation in A divided by the elongation in B is

A wire elongates by 1.0 mm when a load W is hanged from it. If this wire goes over a pulley and two weights W each are hung at the two ends, the elongation of the wire will be
