1. The problem statement, all variables and given/known data A uniform 250 kg beam is supported by a cable connected to the ceiling, as shown in the figure. The lower end of the beam rests on a rough, horizontal floor. What is the magnitude of the tension in this cable?

The attempt at a solution I know that this problem is easiest to complete using torques, but I was told to try it without using torque (if possible). That being said, here is my attempt: http://imgur.com/jKr3tDC I know that I got the right answer but I am not sure how. Aren't the 40 degrees and the 20 degrees are the wrong angles to use when using a horizontal/vertically oriented plane?
