The lever where the effort is between the fulcrum and the load is which class?

Explanation:
In levers, the class is defined by where the effort sits relative to the fulcrum and the load. If the effort is placed between the fulcrum and the load, that lever is Class III. This setup means you have a mechanical disadvantage: you must apply more force to lift the same load, but you gain a greater range of motion and speed of movement. It’s a common arrangement in many human movements, like the elbow during a biceps curl, where the muscle force is applied between the joint (fulcrum) and the weight at the hand (load).
