Lever demonstration. A Class 2 lever is demonstrated with a wooden ruler,a 50 g weight and a spring scale. As the distance between the pivot point and the weight (lever arm) is decreased,a smaller force (as measured by the scale) is required to balance the mechanical system. In this photo the scale reads 15 g | |
