compress 1. A mild steel flat 150mm wide x 20mm thick and 6 metres long carries and axial pull of 300 kN. If E = 200 GPa, and Poisson's ratio = 0.26m calculate the = change in length, width, thickness and volume of the flat. Ans : 3 mm, 0.0915mm, 0.0026mm and 4320mm'. 2. A composite bar 30 mm diameter and 600 mm long made of steel is enclosed in a brass tube having external diameter 60 mm and 8 mm thick. If temperature is raised to 80° C, then calculate the stresses induced in each material. 1 Take az = 12 x 10-6 /°C, a = 19 x 10-6 /°C and E C = 200 GPa, m = 1/2
