1. Assume length of the m-tape steel weighs 12.5g/m and has a cross section of 0.022 cm². It measures correctly when supported throughout under a tension of 8.0 kg and at a temperature of 20°C. When used in the field, the tape is only supported at its end, under a pull of 9.0 kg, and at only supported at an average temperature of 28°C. Determine the distance.

Load P is applied to joint D and the temperature increases by 50 °F. There are two steel (E = 29*10^6 psi; a = 6.5*10^-6/°F) AD and DC and a bronze (E = 16*10^6 psi; a = 9*10^-6/°F) BD with a length of 50 inches. Each bar is a 0.75 inch diameter. Find the deformation of every rod, the displacement at D, and the stress in each rod.
