A material has Poisson's ratio 0.5. If a uniform rod of it suffers a longitudinal strain of 2 x 10^{- 3} , then the percentage change in volume is

The length of a wire increases by 1% by a load of 2 kg-wt. The linear strain produced in the wire will be

A wire of diameter 1 mm breaks under a tension of 1000 N. Another wire of same material as that of the first one, but of diameter 2 mm breaks under a tension of

A wire is stretched to double its length. The strain is

The property of a body by virtue of which it tends to regain its original size and shape of a body when applied force is removed, is known as

Young's modulus of a wire depends on

A spring of force constant k is cut into two equal parts. The force constant of each part is

A wire suspended vertically from one end, is stretched by attaching a weight 200 N to the lower end. The weight stretches the wire by 1 mm. The energy gained by the wire is

Elastic limit is equal to

Young's modulus of a material has the same unit as

With the increase in temperature, the Young's  modulus of a material 

A rope of nylon of radius 1.5cm has a breaking strength of 1.6 x 10⁵N.The breaking strength of a similar rope of radius 7.5mm shall be

The value of Bulk modulus for a perfectly right body is

The energy stored in a stained wire is given by

The reciprocal of Bulk modulus (1/K) is called
