The mechanical system consists of two identical steel rods (A = 30 mm', E= 20OGPA, a = 15x10/°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. %3D -200 mm 80 mm B.
