Question 1
A copper tube having a cross-sectional area of 2000mm2 and length of 300 mm is placed between two rigidcaps. Four 22 mm diameter steel bolts are symmetrically arrangedparallel to the axis of the tube and are lightly fastened.Calculate:
- The stress in the tube if the temperature of the assembly israised by 700C.
- The load each bolt will carry at the raisedtemperature.                                Â
           EST = 200 GPa;  αST = 12 x10-6 /0C        Â
          ECU = 100 GPa;  αCU = 16 x10-6 / 0C
