A rigid bar is supported by two copper r
ods and the gap (A) between the alumin
um rod and the bar is 1.50 mm. If the te
mperature for all materials is increased
by 40 degrees Celsius, will the aluminu
m rod touch the rigid bar or not? Prove y
our answer by stating computed data. D
isregard the weight of the rigid bar.
For each copper bar,
-
A = 500 mm^2, E = 120 GPa, and a = 16.
8 μm/(m. C).
For the aluminum bar,
A = 400 mm^2, E = 70 GPa, and a = 23.1
