The rigid bar AD is pinned at A and attached to the bars BC and ED, as shown below. The entire system is initially stress free and the weights of all bars are negligible. The temperature of bar BC is lowered 25°C and that of the bar ED is raised 25°C. Neglecting any possibility of lateral buckling, find the normal stresses in bars BC and ED. For BC, which is brass, assume E = 90GPa, a = 20x 10-6/°C, and for ED, which is steel, take E = 200 GPa and a = 12x10-6/°C. The cross-sectional area of BC is 500 mm2 and of ED is 250 mm2.
