Question

A copper rod of 50 mm diameter meter and 1 meter long is fixed in a hollow steel rod of 100 mm external diameter and 50 mm internal diameter and fixed from ends to form a compound bar. If a tensile load of 50 kN acts at the ends in such a way that extension in both the rod is the same, then calculate the load taken by each. Take E(copper) = 75 GPa and E(steel) = 180 GPa.
