Suppose we wish to use a 2.0 m iron bar to lift a heavy object by using it as a lever. if we place the pivot point at a distance of 0.3 m from the end of the bar that is in contact with the load and we can exert a downward force of 522 n on the other end of the bar, find the maximum load that this person is able to lift (pry) using this arrangement (neglect the mass of the bar in this problem)
