A solid copper cube has an edge length of 85.5cm. How much pressure must be applied to the cube to reduce the edge length to 85.0cm? The bulk modulus of copper is 1.4 *10 11 Nm -2.
thanks for the answer.
according to Hooke's law,
σ = E ε
σ = E ΔL/L
σ = (1.4 *10^11)(85.5)/85
σ = 1.40824 * 10^11 N/m²
σ = 1.40824 * 10^5 MPa
