What is the primary function of a Class 2 lever?

A Class 2 lever is characterized by having the load positioned between the effort (the force applied) and the fulcrum (the pivot point). The primary function of this type of lever is to provide a mechanical advantage, allowing a smaller applied force to lift a larger load. This is achieved because the distance from the fulcrum to the point where the force is applied is longer than the distance from the fulcrum to the load itself.

In a Class 2 lever, as the effort is applied, the lever rotates around the fulcrum, effectively lifting the load. This setup allows for more efficient lifting and enables users to move heavy objects with less effort than would be needed without a lever. This is particularly useful in tools and equipment designed for lifting or moving heavy loads, such as wheelbarrows.

The other answer choices describe different lever configurations or functions that do not accurately represent the mechanics of a Class 2 lever.
