Question

Define volume strain.

Answer 1

the volumetric strain is defined as follows: Volumetric Strain: The volumetric strain is the unit change in volume, i.e. the change in volume divided by the original volume

Answer 2

Answer:

$volumetric\ strain = \frac{chnage\ in\ volume}{original\ volume}$

Explanation:

Since we know that the strain is defined as the change in physical quantity to the original quantity.

Volumetric strain is defined as the ratio of change in volume to the original volume.

$volumetric\ strain = \frac{chnage\ in\ volume}{original\ volume}$.............................(1)

As per the equation (1) we can say that Volumetric strain is the unit less quantity.It has no unit.It is also a dimension less quantity.
