Use this wooden demonstration model to illustrate the concept that the further from the pivot point a force is applied, the greater its effect. This basic principle is behind the operation of the lever and many other basic devices. This model allows students the chance to freely experiment with this idea, by moving masses back and forth and looking for the point of balance.
