Question: A uniform cube is subjected to volume compression. If each side is decreased by 1%, then bulk strain is
[EAMCET (Engg.) 1995; DPMT 2000]
Options:
A) 0.01
B) 0.06
C) 0.02
D) 0.03
Show Answer
Answer:
Correct Answer: D
Solution:
If side of the cube is L then $ V=L^{3} $
Therefore $ \frac{dV}{V}=3\frac{dL}{L} $ \ % change in volume = 3 × (% change in length) = 3 × 1% = 3% \ Bulk strain $ \frac{\Delta V}{V}=0.03 $
