There is a picture of the problem.

Here are the formulas i can get from that:

The sum of the forces in the y direction with positive being upward
cos 36.9 * Tension 1 + cos 53.1 * Tension 2 - m * g = 0

The sum of the forces in the x direction with positive being to the right
sin 36.9 * Tension 1 + sin 53.1 * Tension 2 = 0

The sum of the torques with clockwise being positive
cos 53.1 * Tension 2 * (6.1 - x) + cos 36.9 * Tension 1 * x

This leads me with 4 variables and 3 equations.
Tension 1, Tension 2, m (mass), and x

Maybe this problem is more simple than the approach i'm taking?

Calculate the torque about the left end of the bar. That should help.

You have to take in consideration the torques of either side because they have to equal zero.

i got the equation x*m*g=Tension 2*cos 53.1*6.1

what is possible to solve for???

Well, now you have an expression for x in terms of m and Tension 2. Find out what these are and you're done (i.e. use the other equations you have).
