Determine the reactions and bar forces that are created in the truss in Figure P9.30 when the top chords \((A B C D)\) are subjected to a \(50^{\circ} \mathrm{F}\) temperature increase. Given: \(A E\) is constant for all bars, \(A=10\) in. \(^{2}, E=30,000\) kips/in. \({ }^{2}\), and \(\alpha=6.5 \times 10^{-6}\) (in./in.)/ \({ }^{\circ} \mathrm{F}\).
