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:  = 3600 in.4,  =  = 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,  = 400 in.4, and  = 8 in.2; E = 30,000 kips/in.2.
