A rigid bar AB is hinged at A and supported by a copper rod 2 m long and steel rod 1 m long. The bar carries a load of 20 kN at D as shown in Fig. 4.21.If the cross-sectional areas of steel and copper rods are 200 mm2 and 400 mm2 respectively, find the stresses developed in each rod. Take the values of E for steel and copper as 200 GPa and 100 GPa respectively.
