A uniform cube is subjected to volume compression. If each side is decreased by 1%, then bulk strain is
Text Solution
Verified by ExpertsThe correct answer is:
D
If side of the cube is L then $V = L^3$ ⇒ ⇒ $\frac{\mathrm{d}V}{V} = 3 \frac{\mathrm{d}L}{L}$
∴ ∴ % change in volume = 3 × (% change in length)
= 3 × 1% = 3% ∴ ∴ Bulk strain $\frac{\Delta V}{V} = 0.03$
