Determinethe volume contraction of a solid copper cube, 10 cm on an edge, whensubjected to a hydraulic pressure of 7.0 ×106Pa.
Length of an edge of the solid copper cube, l = 10 cm = 0.1 m
Hydraulic pressure, p = 7.0 ×106 Pa
Bulk modulus of copper, B = 140 × 109 Pa
Where,
= Volumetric strain
ΔV = Change in volume
V = Original volume.
Original volume of the cube, V = l3
Therefore, the volume contraction of the solid copper cube is 5 × 10–2 cm–3.
