1.	A uniform cube is subjected to volume compression. If each side is decreased by 1%, then bulk strain is:
Answer» 0.01 0.02 0.06 0.03 Solution :If side of the cube is L then, `V=L^(3)` `RARR""(dV)/(V)=3(dL)/(L)` `THEREFORE%"CHANGE in volume"=3xx(%"change in length")` `=3xx1%=3%` `therefore"Bulk strain"(DeltaV)/(V)=0.03`
