Question

define volume strain​

Answer 1

a strain equals to the ratio between the change in volume of an object and its original volume. also called bulk strain

Answer 2

Answer:

volume strain:- A strain equal to the ratio between the change in volume of an object and its original volume. Also called bulk strain .Within elastic limit, the ratio of volumetric stress to the corresponding volumetric strain in a body is always constant, which is called as Bulk modulus of elasticity. It is denoted by letter 'K'. Its S.I. Unit of stress is N m-2 or Pa (pascal) and its dimensions are [L-1M1T-2].
