A rigid bar is supported by two copper ro
ds and the gap (A) between the aluminu
m rod and the bar is 1.50 mm. If the temp
erature for all materials is increased by 4
0 degrees Celsius, will the aluminum rod
touch the rigid bar or not? Prove your ans
wer by stating computed data. Disregard
the weight of the rigid bar.
For each copper bar,
A = 500 mm^2, E = 120 GPa, and a = 1
6.8 μm/(m. C).
For the aluminum bar,
A = 400 mm^2, E = 70 GPa, and a = 23.
