The wires AB and AC are made of steel, and wire AD is made of copper. Before the 150-lb force is applied, AB and AC are each 60 in. long and AD is 40 in. long. If the temperature is increased by 80°F, determine the force in each wire needed to support the load. Each wire has a cross-sectional area of 0 0123 in2. Take Est = 29(103) ksi, Ecu = 17(103) ksi, αst = 8(10-6)/°F, αcu = 9.60(10-6)/°F.
