What type of lever has the effort force between the fulcrum and the resistance force?

In a lever system, the arrangement of the fulcrum, effort force, and resistance force defines the type of lever. For a lever where the effort force is located between the fulcrum and the resistance force, we are looking at a specific configuration.

In a third-class lever, the effort is applied between the fulcrum and the load (or resistance). This type of lever is commonly seen in situations like a pair of tweezers or your forearm when lifting an object, where the elbow serves as the fulcrum, the effort is provided by the muscles in the arm, and the load is in the hand.

The defining characteristic of a third-class lever is this positioning, which maximizes the distance the load moves compared to the distance the effort moves, allowing for greater speed and range of motion rather than mechanical advantage. This is why it is correctly identified in your answer.

Understanding the arrangement in the other types of levers can clarify the differences: in first-class levers, the fulcrum is between the effort and the load; in second-class levers, the load is between the fulcrum and the effort; and a fourth-class lever is not commonly categorized in the traditional lever classification system used for first
