SITUATION 1: The wires AB and AC are made of steel, and wire AD is made of copper. Before the 0.150-kip force is applied, AB and AC are each 5 ft. long and AD is 3% ft. long. The temperature is increased by 27°C. E. = 29 x 105 ksi, E... 17 x 105 ksi, a... = 8 x 10° /F, 9.60 x 100/F. Each wire has a cross-sectional area of 0.0123 in². Determine the force in each wire needed to support the load. . 45 45° A 150 lb
