2 - The rigid bar ABC in Figure is pinned Steel Aluminum at B and attached to the two vertical L = 0.5 m L= 1.5 m rods. Initially, the bar is horizontal and the vertical rods are stress-free. A = 500 mm? A = 1500 mm? Determine the stress in the aluminum rod if the temperature of the steel rod is decreased by 40°C. Neglect the weight of bar ABC. (30 Points) Steel Aluminum E = 200 x 10° N/m2 a = 11.7 um/(m- °C) E = 70 x 10° N/m2 a = 23 um/(m-°C) B A 0.6 m 1.2 m
