Question
As shown in the figure, 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 each rod when
the temperature in the assembly is
increased to 95°C. For each copper
bar, A= 500 mm2, E = 120 GPa, and a
= 16.8 µm/(m °C). For the aluminum
bar, A = 400 mm2, E = 70 GPa, and a
= 23.1 µm/(m °C).
