Product Details

Easily illustrate the concepts of balance and rotational motion with this long, 60-cm lever arm. Students can now effortlessly experiment with first-, second- and third-class levers and see the relationships between distance, mass and the position of the fulcrum. Introductory classes will gain firsthand knowledge of mechanical advantage. More advanced classes will experiment with torque and determine the necessary conditions to maintain balance. The Flinn PSWorks™ Lever Arm quickly attaches to the PSWorks™ Support Stand, not included. Additional materials needed are weight hangers, weights and string.
