![2.1 (A). A power transmission cable consists of ten copper wires each of 1.6 mm diameter surrounding three steel
wires each of 3 mm diameter. Determine the combined E for the compound cable and hence determine the extension
of a 30 m length of the cable when it is being laid with a tension of 2 kN.
For steel, E = 200 GN/m?; for copper, E = 100 GN/m?.
