A lever pivots on a support called a fulcrum. (as shown in the picture)
For a balanced lever, the distance d (in feet) an object is from the fulcrum varies inversely with the object's weight w (in pounds). An object weighing 140 pounds is placed 6 feet from a fulcrum. How far from the fulcrum must a 112 pound object be place to balance the lever?
