A steel bar is placed between two copper bars, each having the same area and length as steel bar at 20℃. A this stage, they are rigidly connected together at both the ends. When the temperature is raised to 320℃, the length of the bars increases by 1.5mm. Determine the original length and final stresses in the bars. Steel: Coefficient of expansion = 0.000012/℃; Es = 210 GN/m^2 Copper: Coefficient of expansion = 0.0000175/℃; Ec = 100 GN/m^2
