Answer 1

A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.

What is Volume?

Volume is the space occupied by a three-dimensional object.

Given that, the side cube is l, then

volume V = l³

$\dfrac{\Delta V}{V} = \dfrac{3D1}{1}$

For change in volume

% Change in volume = 3× % change in length

= 3 × 1%

Hence, bulk strain = 0.03.



Thus, the bulk strain is 0.03.
