    A uniform cube is subjected to volume compression. If each side is decreased by 1%, then bulk strain is

    A) 0.01 

    B) 0.06 

    C) 0.02 

    D) 0.03

    Correct Answer: D

    Solution :

    [d] If side of the cube is L. then \[V={{L}^{3}}\] \[\Rightarrow \frac{dV}{V}=3\frac{dL}{L}\] % change in volume\[=3\times \] (% change in length) \[=3\times 1%=3%\]             \[\therefore \,\,Bulk\,strain\,\,\frac{\Delta V}{V}=0.03\]
