Question

The two cylindrical rod segments shown in the figure below (Figure 1) are fixed to the rigid walls such that there is a gap of 0.01 in. between them when T1=75 degrees F . Each rod has a diameter of 1.5 in. Take αal=13(10^-6)/∘F ,Eal=10(10^3)ksi, (σY)al=40ksi, αcu=9.4(10^−6)/∘F, (σY)cu=50ksi, and Ecu=15(10^3)ksi.

a) What larger temperature T2 is required in order to just close the gap?

b) Determine the magnitude of the average normal stress in each rod if T2=350∘F
