6. Three wires are used to support the 150-lb force. The wires AB and AC are made of steel, and wire AD is made of copper. Assume that the three wires have constant cross-sectional area A = 0.0123 in?. For steel wire, a = 8 x 10* in/ (in'F ) and E = 29000 ksi and for copper wire, a = 9.6 x 10 in/ (in°F ) and E = 17000 ksi.
