If a load of 60kN is applied to a rigid bar suspended by 3 wires as shown in the below figure what force will be resisted by each wire?
The outside wires are of Al, cross-sectional area 300mm2 and length 6m. The central wire is steel with area 200 mm2 and length 8m.
Initially there is no slack in the wires
E = 2 $\times$105 N/mm2 for Steel
E = 0.667×105 N/mm2 for Aluminium.
