A compound bar is made of a steel plate 50 mm wide and 10 mm thick to which copper plates of size 40 mm wide and 5 mm thick are connected rigidly on each side as shown in figure. The length of the bar at normal temperature is 1 m. If the temperature is raised by 80°C, determine the stresses in each metal and the change in length. Given a = 12 x 10-6/°C, α = 17 × 10-6/°C, E = 2 × 10³ N/mm², E = 1 × 10³ N/mm². S Copper Steel Copper
