The mechanical system consists of two identical steel rods (A = 30 mm?, E = 200GPA, a = 15×106/°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 e through which the beam AC would rotate due to this temperature change. -200 mm -80 mm A B -"Rigid" |(1) (2) 250 mm
6.13 A brass rod is a firm fit inside a steel tube 2 cm inside diameter and 4 cm outside diameter when the materials are at 15°C. If the rod and tube are now heated to a temperature of 150° C, calculate the maximum stresses in the brass and steel. Take the coeffi- cient of expansion for steel and brass as 10.8 × 10-6 and 18 x 10-6 per °C respectively. For steel E = 200 GPa and for brass E = 85 GPa. Poisson's ratio for both = 1/3.
