Homework Equations
The Attempt at a Solution
1. I first found the angles each cable made with the pillar.
2. With these angles I found the components of the forces in the x and y direction.
3. So ∑Fx and ∑Fy were found.
4. Then using these values I equated that
## F = \sqrt(F_x ^2 + F_y ^2) ##
5. The from here I subbed Fb and Fc = Fa and that F = 200kN Then rearranging to get Fa I got Fa = 112.36N however it should be 68.4kN.
I am unsure where I have gone wrong. Note vectors are not to be used to solve problem i.e using i, j and k components.
