5. The rigid bar is supported by a smooth pin and two rods as shown. Neglect the weight of the rigid bar. The assembly is initially stress-free. Determine the stress in each rod if the temperature increases by 25°C after a load W = 100 kN is applied. The steel rod has an area of 320 mm? with a = 11.7 µm/ ( m°C ) and E = 200 GPa. For the bronze rod, it has an area of 1380 mm? with a = 18.9 µm/ ( m°C ) and E = 83 GPa. Bronze 3 m Steel 1.5 m E 1.0 m Te 2.5 m +1.5 m W
