  4. Levers can be classified into three different types or classes.

  5. First Class Levers • In a Class 1 lever, the fulcrum is between the effort and the load. EFL LFE

  6. First Class Levers • Examples of common tools (and other items) that use a type 1 lever include:

  7. Second Class Levers • In Class 2 levers, the load is between the fulcrum and the effort. ELF FLE

  8. Second Class Levers Examples of common tools that use a type 2 lever include:

  9. Third Class Levers • In Class 3 levers, the effort is between the fulcrum and the load. LEF FEL

  10. Third Class Levers • Examples of common tools that use a type 3 lever include:
