In a third-class lever system, where is the fulcrum located?

In a third-class lever system, the correct placement of the fulcrum is at one end of the lever. This type of lever is characterized by the effort being applied between the fulcrum and the load. When the fulcrum is positioned at one end, this arrangement allows for a greater range of motion and increased speed of the load being moved, making third-class levers particularly effective for activities that require a quick response or greater distance covered by the load.

The arrangement can be visualized easily with examples like a fishing rod or a broom, where the fulcrum is at one end, the effort is applied in the middle, and the load is situated at the other end. This configuration emphasizes the mechanical advantage of moving the load quickly and covering long distances, although it may require more effort compared to other types of lever systems.
