Please see the attached file.
First call F1 vertical force on hinge, F2 horizontal force on hinge and Ft tension in string.
Call hinge x=0 so ...
This solution is provided in 105 words in an attached .doc file. It uses a simple calculation for finding torque, and then uses this information to find tension in the string and the horizontal and vertical forces on the hinge.
