This is the problem:
http://oi47.tinypic.com/6qij4o.jpg
I set fx, fy, and B equal to zero.
'x' forces: Fx - Bsin(30) = 0
'y' forces: Fy - mg + B(cos(30)) = 0
lower end: -0.5*mg(cos(30)) + 0.4*B = 0
Using the third equation I solved for B, and got -477.4.
I then plugged B into the first two equations and calculated Fy=854.4 and Fx=-238.7.
I don't feel confident in these numbers, so I wanted to double check with someone who has a better understanding. Did I go wrong somewhere, or does this look okay?
Thanks in advance, I really appreciate your help.
