A brass rod having a diameter of 4 in and a length of 40 ft is suspended vertically from one end. It supports a tensile load of 20 kips at the lower end. If the unit mass of brass is 525lb/ft cube and E=140,000ksi. a. Find the elongation of the rod due to self-weight. b. Find the elongation of the rod due to applied load. c. Find the elongation of the rod if it has a coefficient of thermal expansion of 10 μin/(in°F), and if there’s an increase in temperature by 50 °F. d. What is the total elongation due to loads and temperature?
