Question 1

A copper tube having a cross-sectional area of 2000 mm² and length of 300 mm is placed between two rigid caps. Four 22 mm diameter steel bolts are symmetrically arranged parallel to the axis of the tube and are lightly fastened. Calculate:

The stress in the tube if the temperature of the assembly is raised by 70⁰C.
The load each bolt will carry at the raised temperature.

E_ST = 200 GPa; α_ST = 12 x 10^-6 / ⁰C

E_CU = 100 GPa; α_CU = 16 x 10^-6 / ⁰C
