Examples of first class lever?

1. Seesaw: The seesaw is a classic example of a first-class lever. The fulcrum is located in the middle, with the effort (person pushing down on one end) and the load (person sitting on the other end) on opposite sides.

2. Scissors: Scissors are another example of a first-class lever. The fulcrum is located at the point where the two blades are connected, with the effort (your fingers pushing the handles together) and the load (the material being cut) on opposite sides.

3. Crowbar: A crowbar is a tool that is used to pry or lift heavy objects. It consists of a long rigid bar with a fulcrum at one end, the effort applied at the other end, and the load in between. By applying force to the long end of the crowbar, you can lift heavy objects with less effort.
