SITUATION 1: The rigid bar ABC in Figure 1 is pinned at B and attached to the two vertical rods. Initially, the bar is horizontal, and the vertical rods are stress-free. Determine the stress in the aluminum rod if the temperature of the steel rod is decreased by 30°C. Neglect the weight of bar ABC. Aluminum dilly L = 0.9 m A A = 900 mm² E = 70 GPa a = 23 µm/m°C 0.4 m B Steel L = 1.2 m A = 300 mm² E = 200 GPa a = 11.7μm/m°C 0.8 m C
