Problem (8) The rigid bar ABC in the figure is Figure P-268 pinned at B and attached to the two vertical rods. Initially, the bar is horizontal and the vertical rods are Aluminum Steel L = 0.9 m A 300 mm? E = 200 x 10° N/m2 a = 11.7 um/(m-°C) L = 1.2 m A = 1200 mm2 E = 70 x 10° N/m2 a = 23 um/(m-°C) stress-free. 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. C Solution: 0.6 m 1.2 m
