[PLAIN]http://img830.imageshack.us/img830/1091/unled2cjt.jpg [Broken]

2. Relevant equations

I used sum of forces in x y direction and sum of moments

3. The attempt at a solution

So my problem here is that I solved for Ay (1275.3N) and now I have to solve for T

The obvious approach would be to use sum of forces in x direction after doing sum of forces in y to find B. Well I did that and found that B = 2550.6 which is double Ay and equal to mg. B is also perpendicular to the bridge thing. Now when I do sum of forces in x direction i do T = Bcos30 but that's wrong apparently.

Which part am I doing wrong? Is my B wrong?

I calculated B like so:

Fy:0 = Ay - mg + Bsin30

Please help :)
