The rigid bar ABC is supported by a pin at B and two vertical steel rods. Initially the bar is horizontal and the rods are stress-free. Determine the stress in each rod if the temperature of the rod at A is decreased by 40°C. Neglect the weight of bar ABC. Use a-10.7 x 10C and E-200 GPa for steel. ( A-1500 mm A- 500 mm 1.5 m Im 0.8 m-- 1.5 m
