Which list correctly orders effort (E), fulcrum (F), and load (L) for each lever class?
The three types of lever classes are as follows:
1. First Class Lever: In this lever class, the fulcrum is located between the effort and the load. The correct order is FLE (Fulcrum, Load, Effort).
2. Second Class Lever: In this lever class, the load is located between the fulcrum and the effort. The correct order is FEL (Fulcrum, Effort, Load).
3. Third Class Lever: In this lever class, the effort is located between the fulcrum and the load. The correct order is ELF (Effort, Load, Fulcrum).
