Problem 1 Stress Strain Relations - Exercise session at Lappeenranta University of Technology

A metallic bar 300 mm x 100 mm x 40 mm is subjected to a force of 5 kN (tensile), 6 kN (tensile) and 4 kN (tensile) along x, y and z directions respectively. Determine the change in the volume of the block. Take E =2 x 10^5 N/mm^2 and Poisson's ratio = 0.25.
