Before the load W was attached, the bar was horizontal andAL = 6 ftL= 4 ftthe rods were stress-free. Determine the load in rod at A if W = 990O Ib.FA =Answer:4 ft4 ft2 ftWW= 20000 N2. There is a gap between the aluminum bar and the rigid slab that issupported by two copper bars. At 10°C, A = 0.18 mm. Neglecting themass of the slab, calculate the stress in the aluminum rod when thetemperature in the assembly is increased to 105°C. For each copper bar,A = 500 mm?, E = 120 GPa, and a = 16.8 µm/(m.°C). For the aluminumbar, A = 400 mm?, E = 70 GPa, and a = 23.1 um/(m-°C).Answer:Oal =AluminumCopper750 mm
