Problem 2 The mechanical system consists of two identical steel rods (A = 30 mm2, E = 200GPA, a = 15x106/°C) and a "rigid" beam AC. The beam is supported by a smooth pin at B. The nuts at A and C are initially tightened just enough to remove the slack, leaving the two rods stress-free. 1- Determine the axial stresses induced in rods (1) and (2) if the temperature of both rods is decreased by 60°C. 2- Determine the (small) angle 0 through which the beam AC would rotate due to this temperature change. -200 mm 80 mm A В -"Rigid" |(1) (2) 250 mm
