Law of the Lever The figure shows a lever system, similar to a seesaw that you might find in a children’s playground. For the system to balance, the product of the weight and its distance from the fulcrum must be the same on each side: that is, w 1 x 1 = w 2 x 2 This equation is called the law of the lever and was first discovered by Archimedes (see page 787). A woman and her son are playing on a seesaw. The boy is at one end, 8 ft from the fulcrum. If the son weighs 100 lb and the mother weighs 125 lb. where should the woman sit so that the seesaw is balanced?
