1. In Figure P4.111 determine the tensions in cables BC and BE. Neglect the weights of all members and assume that the support at A is a ball-and-socket joint. The 5200-N force has no x component.

(picture is attached below)

2. [tex]\Sigma[/tex] F_{x}= 0

[tex]\Sigma[/tex] F_{y}= 0

[tex]\Sigma[/tex] F_{z}= 0

[tex]\Sigma[/tex] M_{D}= 0

3. The attempt at a solution

Okay so I figured out the angles of the cables and did the sum of the forces.

I had trouble figuring out the sum of the moments.

Here is what I have so far:

[tex]\Sigma[/tex] F_{x}= 0 --> Ax + T1*cos(26.6) = 0

[tex]\Sigma[/tex] F_{y}= 0 --> Ay + T1*sin(26.6) + T2*cos(18.4) + 5200*cos(22.6)= 0

[tex]\Sigma[/tex] F_{z}= 0 --> Az + T2*sin(18.4) + 5200*sin(22.6) = 0

T1 is the cable from B to E

T2 is the cable from B to C

Anything you guys can do to help would be much appreciated, thanks!
