In a First Class lever, where is the fulcrum located?

In a First Class lever, the fulcrum is positioned at one end of the lever arm, with the load located at the opposite end. This configuration allows for the application of effort on the lever arm to balance or lift the load on the other side. The positioning of the fulcrum at one end is crucial because it allows the lever to take advantage of the distances from the fulcrum to the effort and load, creating a mechanical advantage that makes it easier to move heavy objects.

In this arrangement, when the effort is applied at the opposite end from the load, it results in a seesaw effect where the lever pivots around the fulcrum. This setup is commonly seen in tools such as seesaws or scissors, where the load is on one side and the effort is applied on the other side of the fulcrum, allowing for efficient movement and lifting of the load.
