Determine the reactions in the rigid frame in Figure P9.47.

In addition to the applied load, the temperature of beam \(B C\) increases by \(60^{\circ} \mathrm{F}\). Given: \(I_{B C}=3600 \mathrm{in} .{ }^{4}\), \(I_{A B}=I_{C D}=1440\) in. \(.^{4}, \alpha=6.5 \times 10^{-6}\) (in./in.) \(/{ }^{\circ} \mathrm{F}\), and \(E=30,000\) kips/in. \({ }^{2}\).
