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 steelE [151.3 GN/m²; 9.6 mm.] 200 GN/m2. for conner E 100 GN/m²

9:47 1 Oleksandr 03/08/2021, 4:52 p.m. Problems 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/m2; for copper, E = 100 GN/m2. [151.3 GN/m2; 9.6 mm.] 2.2 (A). If the maximum stress allowed in the copper of the cable of problem 2.1 is 60 MN/m?, determine the maximum tension which the cable can support. [3.75 kN.) 3.44p 7 x 10-°x 30 x 200 x 109 200 x 10°
