Question: 1. Determine the reactions in the rigid frame in Figure P9.47. In addition to the applied load, the temperature of beam BC increases by 60°F. Given: IBC = 3600 in.4, IAB = ICD = 1440 in.4, α = 6.5 × 10-6 (in./in.)/°F, and E = 30,000 kips/in.2.

2. Determine the reactions at supports A and E in Figure P9.48. Area of bar EC = 3 in.2, IAD = 400 in.4, and AAD = 8 in.2; E = 30,000 kips/in.2.
