For the bar structure shown in Figure P15 -7, element 1 is subjected to a uniform temperature

Question:

For the bar structure shown in Figure P15 -7, element 1 is subjected to a uniform temperature rise of T = 30 Â°C. Let E = 210 GPa, A = 3 Ã— 10-2 m2, and a = 12 Ã— 10-6 (mm/mm)/Â°C. Determine the displacement of node 1 and the stresses in each bar.
