Question

A uniform cube is subjected to volume compression if each side is decreased by 1 then bulk strain is

Answer 1

Given: A uniform cube

Decrease in size of side = 1%

To Find: Bulk Strain

Solution:

Let the side of cube be = l,

Thus,  

volume V = l³  

Change in volume  

ΔV /V =  3dl/l

​Hence,

% Change in volume = 3× % change in length  

= 3 × 1%

Bulk strain =  3/100

= 0.03

Answer: The bulk strain is 0.03
