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:
EST = 200 GPa; αST = 12 x 10-6 / 0C
ECU = 100 GPa; αCU = 16 x 10-6 / 0C
