What is the Summation of Torques Equation for Figure P8.4?

[mandy9008]

Homework Statement

Write the necessary equation of the object shown in Figure P8.4. Take the origin of the torque equation about an axis perpendicular to the page through the point O. (Let counterclockwise torque be positive and let forces to the right and up be positive. Use q for θ and Rx, Ry, Fx, Fy, Fg, l, and g as appropriate in your equations.)

ΣFx=
ΣFy=
Στ=

The Attempt at a Solution

ΣFx = -Rx+Fx=0
ΣFy= Fy+Ry-Fg=0
Στ=

I can't figure out the summation of the torques

For F_g,F_y and F_x, what are the perpendicular distances from O ? (Take the distance 'l' as the hypotenuse of a right angle triangle)
