1. For the roll truss shown in Figure P15–6, bar part 2 is subjected to a unvaried temperature faint of T = 20 C. Let E = 70 GPa, A = 4 10-2 m2, and a = 23 10-6 (mm/mm)/ C. Determine the stresses in each bar and the misplacement of node 1.

2. For the bar organization shown in Figure P15–7, part 1 is subjected to a unvaried temperature agitate of T = 30 C. Let E = 210 GPa, A = 3 10-2 m2, and a = 12 10-6 (mm/mm)/ C. Determine the misplacement of node 1 and the stresses in each bar.
