This video illustrates a Class 1 lever (also known as a first-class lever). In a Class 1 lever, the fulcrum is positioned between the force (effort) and the load (resistance). Classic examples include a seesaw or a crowbar, where applying force on one end moves the load on the opposite side, with the fulcrum in the middle. In this video, the tire acts as the load, the person or point where force is applied serves as the force, and the center labeled fulcrum divides the two. Follow @spacecameocom
