For the system to balance, the product of the weight and its distance from the fulcrum must be the same in the same on each side; that is, w1x1=w2x2 This equation is called the law of the lever and was the first discovered by Archimedes see page 831. A woman and her son are playing on the seesaw. The boy is at the 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?arrow_forward
