Finding the center of gravity & mass by torque?

  1. Oct 14, 2009 #1
    I don't know how to do these kinds of problems; I just need an example of one, could someone just work it out with an explanation?
    Feel free to change the values or whatever.
    This particular problem isn't to turn in, I'm studying for a test on this material.

    A meter stick is pivoted the 50-cm mark but does not balance because of nonconformities in material.
    150 g and 200 g weights ar placed at the 10-cm and 75-cm marks to balance the meterstick.
    When the weights are interchange, the pivot point is at the 43-cm mark.
    find the mass of the stick and the center of gravity.
