A square steel bar of dimension 50 mm × 50 mm × 150 mm is subjected to an axial load of 250 kN. Determine the decrease in length of the bar if (i) the lateral strain is fully prevented by applying external uniform pressure on the rectangular surfaces (ii) only one-third of the lateral strain is prevented by the external pressure E 250 GPa and μ = 0.3
