I'm too lazy to check all of your angles, but it looks reasonable. Just double check your SohCahToa and you should be fine.

It's much easier to do this geometrically: Step 1 - Find the y and z components of the 5200N force. Step 2 - Multiply these by 12m (to get the torque) and divide by 6 m to find the respective forces that the cables need to provide equilibrium. Step 3 - now you have four vectors: BE, BC, F(z)...

Homework Statement A Planck of length L2 leans against a wall. It starts to slip downwards without friction. Show that the top of the plank loses contact with the wall at 2/3 of it's original height. Homework Equations F*R = torque Moment of Inertia of Rod (I) = 1/3 M4L^{2} Mgh =...
