A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.
Volume is the space occupied by a three-dimensional object.
Given that, the side cube is l, then
volume V = l³
[tex]\dfrac{\Delta V}{V} = \dfrac{3D1}{1}[/tex]
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.
