Q The mechanical system, shown in the figure, consists of two identical steel rods (A 60 mm?, E= 200 GPa, a 12 x 10/ °C) and a "rigid" beam AC. The beam is supported by a smooth pin at B. The nuts at A and Care initially tightened just enough to remove the slack, leaving the two rods stress-free. Determine the axial stresses induced in rods (1) and (2) if the temperature of both rods is decreased by 60 °C. %3D -200 mm 80 mm C "Rigid" (1) (2) 250 mm
