Understand the concept of levers in the human body: Levers are simple machines that help in movement, and they consist of a fulcrum (pivot point), an effort (force applied), and a load (resistance).
Identify the three classes of levers: First-class levers have the fulcrum between the effort and the load, second-class levers have the load between the fulcrum and the effort, and third-class levers have the effort between the fulcrum and the load.
Analyze the given problem: The question asks about the type of lever where the force (effort) is applied between the fulcrum and the load.
Relate the problem to the lever classes: Based on the definitions, a third-class lever is characterized by having the effort applied between the fulcrum and the load.
Conclude with the correct identification: Therefore, the type of lever where the force is applied between the fulcrum and the load is a third-class lever.
