Trying To help My Daughter With A Physics ?

  1. Dec 13, 2003 #1
    She has to figure out where to place a second kid on a seesaw to balance the seesaw. They give you the weight of the seesaw in the problem. Is this relevant? Or do you ignore the weight of the seesaw?

    If you place the pivot exactly halfway between the board, and assuming the board is uniform in mass/density, then the force of it's weight will act right on the pivot so it won't cause a torque.. meaning you can pretty much exclude it from the equation
