1. The problem statement, all variables and given/known dataSee figure.

2. Relevant equations

Sum of Fy = 0

Sum of Fx = 0

Tension is constant across the cord, regardless of the number of pulleys.

3. The attempt at a solution

My first thought after looking at the B A E connection to load P was that the hypotenuse of the 60 degree triangle must be 850 newtons since tension is constant across the rope. Is there any flaws in my reasoning? (I can't seem to get the correct answer so there must be )

Also doesn't the tension in the cord ABCD depend on load P as well? The heaver P is, the greather the tension in the cord will have to be to keep the cord-pulley system from moving. I'm not sure what forces I'm suppose to use to obtain a tension across ABCD.

Any help is greatly appreciated.
