Determine the reactions in the rigid frame in figure p947

Question

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: I_BC  = 3600 in.⁴, I_AB = I_CD = 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, I_AD = 400 in.⁴, and A_AD = 8 in.²; E = 30,000 kips/in.².
