Understanding Class Levers

The video introduces a pneumonic device, FLE, to help remember the different classes of levers. FLE stands for Fulcrum, Load, and Effort, indicating what is in the middle of each class lever. The first class lever has the fulcrum in the middle, the second class lever has the load in the middle, and the third class lever has the effort in the middle. This method aids in understanding and recalling the characteristics of each lever class.
