W= 20000 N
2. There is a gap between the aluminum bar and the rigid slab that is
supported by two copper bars. At 10°C, A = 0.18 mm. Neglecting the
mass of the slab, calculate the stress in the aluminum rod when the
temperature 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 aluminum
bar, A = 400 mm?, E = 70 GPa, and a = 23.1 um/(m-°C).
Answer:
Oal =
Aluminum
Copper
