http://img10.imageshack.us/img10/8880/capturejfu.jpg [Broken] I did arctan(12/5) to get the degrees + 180 to get the angle from the X axis to B, then I just split the angles into components. I did 100*cos(246) + 100*cos(theta) = 0, and I got 67 degrees. Then I was doing the Y components, and realized they were equal and opposite, so it would equal 0, which the weight can't be equal to. So I looked at the solution, and here how the answer is found. Sum of X: 100cos(theta) = Wa(5/13) Sum of Y: 100sin(theta) = Wa(12/13)+Wa Why is the answer figured like this, and when do I do it differently from sum of the components? I'm totally lost, but I have a slight idea. Thanks.
