The two cylindrical rod segments are fixed to the rigid walls such that there is a gap of 0.01 in. between them when t1 = 60°f. each rod has a diameter of 1.25 in. determine the average normal stress in each rod if t2 = 400°f, and also calculate the new length of the aluminum segment.

average normal stress = 11.6 ksi

Explanation:

Data:

First, we calculate the thermal expansion required to close the gap:

Next, we determine the resultant compatibility:

The average normal stress:
