Homework Help: Torque/Translation Equilibrium

  1. Sep 27, 2009 #1
    1. The problem statement, all variables and given/known data

    We recently did a lab where we calculated various torque values for various systems. Basically, we attached mass by a hanger at different areas on a balanced/pivoted meter stick.

    At the end of the lab, he asks the question "How is the condition for translation equilibrium Fnet = 0 satisfied in this experiment?

    I think I understand why, but I can't really explain it in a comprehensible manner.

    3. The attempt at a solution

    I believe it is because we're establishing rotational equilibrium and at equilibrium any net force acting on the system is 0 (by definition). But.. how do I explain this? The forces are all different (considering Mass * Acc Due To Gravity), but they even out because they're placed at different distances from the pivot point to put the system into rotational equilibrium.
