Question

a uniform cube is sujected to volume compression if each side is decreased by 1%then bulk strain is​

Answer 1

Answer:

if side of cube = L then volume = V = L3

hence (dV / V) = 3 ∙ (dL / L)

% change in volume = 3 × % change in length given : % change in length = 1%

∴ % change in volume = 3% (ΔV / V) = 0.03

bulk modulus = (ΔV / V) = 0.03
