Define lever classes

Using the Skeletal Lever Systems knowledge point

• First-class lever: The fulcrum (F) is positioned between the effort (E) and the resistance (R) (E-F-R).
• Second-class lever: The resistance (R) is positioned between the fulcrum (F) and the effort (E) (F-R-E).
• Third-class lever: The effort (E) is positioned between the fulcrum (F) and the resistance (R) (F-E-R).

Match the question criteria

The question asks for the class of lever where the fulcrum is located between the effort and the resistance. This matches the definition of a first-class lever.
