Question: 1 7 - A horizontal rigid bar ABC is pinned at end A and supported by two cables at points B and C . A

17- A horizontal rigid bar ABC is pinned at end A and supported by two cables at points B and C. A vertical load P=15kN acts at end C of the bar. The two cables are made of steel with a modulus elasticity E=225 GPa and have the same cross- sectional area. Calculate the minimum cross-sectional area of each cable if the yield stress of the cable is 420Mpa and the factor of safety is 2.1. Consider load P only; ignore the weight of bar ABC and the cables.
