A metallic bar has length, breadth & thickness of 2.5 cm x 1 .0 cm x 5 mm respectively. It is subjected 3 mutually perpendicular loads of 400 kN (Tensile), 2 MN (Tensile), 4 MN (compressive) acting along length, breadth & thickness directions respectively. Find the change in volume. Take E as 200GPa & poisson’s ratio 0.25. Also find the change in Length, breadth & thickness. Also find the change that can be made in the4 MN load, in order that there should be no change in volume.
