The length of a wire under stress changes by `0.01%`.The strain produced is

The length of a brass wire is 1m. The strain produced by a load is 0.001. The change in its length is

3 m long copper wire is stretched to increase its length by 0.3 cm. The lateral strain produced in the wire is,

When a wire is twisted, the strain produced in it is

When a wire is twisted, the strain produced in it is

A wire has Poisson's ratio 0.3 . If the change in the length of the wire on stretching it is 1% then percentage change in the volume of the wire will be

A wire has Piosson's ratio 0.3 . If the change in the length of the wire on stretching it is 1% then percentage change in the volume of the wire will be
