In a Third Class lever, the effort is applied between the load and the fulcrum. This configuration means that when you exert force at the point where the effort is applied, it results in a mechanical advantage that allows the load to be moved more efficiently, though the trade-off is that a larger amount of effort is needed to move a smaller load.

In practical terms, consider a common example like a pair of tweezers or a fishing rod. When you close the tweezers (applying effort in the middle), the tips of the tweezers (where the load is) move in response to this effort. The fulcrum in this scenario is at the end of the tweezers, creating the typical Third Class lever situation where the effort is indeed positioned between the load and the fulcrum.
