Homework Help: Force Left and Right

  1. Nov 6, 2008 #1
    1. The problem statement, all variables and given/known data

    Ten bags of top soil, each weighing 185 N, are placed on a 2.40-m long sheet of wood. They are stacked 0.50 m from one end of the sheet of wood, as shown below. Two people lift the sheet of wood, one at each end. Ignore the weight of the wood, how much force must each person exert?

    2. Relevant equations


    10*185=1850N so that would be the total being liften since the wood is ignored
    From there I am stuck as to do what http://img120.imageshack.us/img120/6727/p827rs8.th.gif [Broken]

    Treat it as a moment arm about one end or the other. Your choice.

    The weight times the distance away from where you choose and the force times the length of the board must match shouldn't they? Since you know the total weight then you know the sum of the lifting forces must equal that.
