Question
Transcribed Image Text:The two cylindrical rod segments shown in the figure below
(Eigure 1) are fixed to the rigid walls such that there is a gap of
0.01 in between them when T₁ = 80°F. Each rod has a
diameter of 1.7 in. Take cal = 13(10-6)/°F.
Eal = 10(10³) ksi, (y)al = 40 ksi, acu = 9.4(10-)/°F.
(ay)eu = 50 ksi, and Ecu = 15(10³) ksi.
