Homework Help: Torque and center of mass

  1. Jul 1, 2010 #1
    In the following question, I'm unable to find the center of mass to do the Torque calculation:

    Two 59.0 N forces are applied in opposite directions to the 13.6 cm long figure shown. If the angle θ=37.0°, what is the net torque about the center of mass?

    Hint: These forces form a couple.

    I get that the forces form a couple. I could do the Torque calculation but I can't figure out the center of mass of the object

    Does it matter? Hint: Try finding the torque about two different points.
