The Attempt at a Solution
By just looking at the picture I was able to generate 2 equations but I seem to have 3 unknowns so I'm sort of stuck right now. Here are my equations:
[tex] 50 = T_{ba}sin(130) + T_{bc}sin(\alpha) [/tex] and,
[tex] 40 + T_{bc}sin(180+\alpha) = T_{cd}sin(50)[/tex]
Any ideas of anything I'm missing? Am I taking the correct approach to this problem? Is there a simplier way!?
Thanks,
