In a first-class lever, where is the fulcrum typically located?

In a first-class lever, the fulcrum is typically located in the middle of the lever. A first-class lever is characterized by having the fulcrum positioned between the effort (the force applied) and the load (the resistance being moved). This configuration allows for the load and effort to be on opposite sides of the fulcrum, enabling a balance that can provide mechanical advantage.

When the effort is applied to one side of the fulcrum, the lever pivots around the fulcrum point, lifting the load on the opposite side. A classic example of a first-class lever is a seesaw, where the fulcrum is placed in the center, allowing two children sitting at either end to balance and lift each other.
