Hey guys
Im having problems figuring out this Statics question
I feel like I can solve it, But it has been bugging me for weeks
Here it is. and Here is a quick FBD and notes I posted from others
Would Anyone let me know If the FBD is correct?
Im not asking for the answer. I honestly just want to learn the correct process to accomplish this question. THX

Right: handwritten free-body diagram with forces FCx, FCy, FDx, FDy, FBx, FBy, FEx, FEy, FFx, FFy, FGy=15kN and 15kN, dimensions 1.2m, 3.2m and .8m.

Nobody?

First start with body CBA and take it from there. This problem is simply laborious nothing else.

OK
So I don't start with the Reactions at E and F?

Having a hard time Isolating for EX

Typed worked solution of a moment equilibrium problem: four numbered equations (Eqn. 1 to Eqn. 4) followed by algebra summing moments about point E, substituting Eqn. 2 and Eqn. 3 into Eqn. 1 and then into Eqn. 4, ending with Ey = -P - Ex1.333 and a final line of 0 = 0.

Nevermind. Figured it out. I over engineered the first part. It was quite simple
