First Class Lever 3D model

The first class lever is the one you may be most familiar with. It uses a fulcrum in between, and the applied force and load are at opposite ends. The diagram at the left shows a first class lever set up to move a heavy load with a small applied force. A first - class lever looks like a seesaw. The effort (applied) force and resistance force (load) are at opposite ends with the fulcrum somewhere in between. Crowbars and scissors are examples of first - class levers. ... Baseball bats, oars, and shovels are examples of third- class levers.
