In a second-class lever system, where is the load positioned?

In a second-class lever system, the load is positioned between the fulcrum and the effort. This arrangement allows for greater mechanical advantage, meaning the effort applied can lift a heavier load. The fulcrum acts as the pivot point, while the effort is applied on one end of the lever. Because the load is located between these two points, the force exerted can effectively overcome the weight of the load, enabling the lifting motion.

This system is commonly seen in various practical applications, such as wheelbarrows, where the wheel serves as the fulcrum, the load is placed in the middle, and the user lifts on the handles at one end to elevate the load. This configuration maximizes efficiency and reduces the effort needed to move the load.
