A power transmission cable consists of ten copper wires each of 1.6 mm diameter surrounding three steelwires each of 3 mm diameter. Determine the combined E for the compound cable with an 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/m2; for copper, E = 100 GN/m2. 149.3 GN/m2 150.3 GN/m2 C) 152.3 GN/m2 D) 151.3 GN/m2
