Problem 1: A steel rod with a cross-sectional area of 0.20 in´ is stretched between two fixed points. The tensile load at 65°F is 1250 lb. What will be the stress at 0°F? At what temperature will the stress be zero? Assume a = 6.5×10° in / (in.°F) and E = 29 x 10° psi.
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. Neglect longitudinal frictional forces between the rod and the tube. %3D eleo
