lever
A lever is a simple machine that allows mechanical force to be exerted using a varying distance. Typically, the lever allows the use of a smaller force across a greater distance in the place of a larger force over a smaller distance.
A class 1 lever does not multiply input force. In this type of lever, the fulcrum is positioned between the effort force and the load, resulting in no mechanical advantage gained. An example of a class 1 lever is a see-saw.
Multiply (the input force) x (the lever's mechanical advantage).

The mechanical advantage gained by using a lever is determined by the ratio of the distance from the fulcrum to the point where the input force is applied compared to the distance from the fulcrum to the point where the output force is applied. This ratio helps multiply the input force to exert a greater output force, making it easier to lift or move heavy objects using a lever.
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
A first-class lever does not necessarily make the force greater. It depends on the placement of the fulcrum and the direction of the applied force relative to the load. A first-class lever can either increase force or increase distance, depending on the specific arrangement of its components.
In a second-class lever, the output force is always greater than the input force because the effort arm is longer than the resistance arm. This mechanical advantage allows the lever to amplify force, making it easier to lift heavy objects.
A lever is an example of a machine that allows force to be applied over a greater distance. By using a lever, a smaller force applied over a longer distance can produce a greater force over a smaller distance on the other side.
Some things that belong to a lever include a fulcrum (the pivot point), an effort force (the force applied to move the lever), a load force (the resistance being moved), and the lever arm (the distance between the fulcrum and where the forces are applied). Lever examples include a seesaw, crowbar, and a pair of scissors.

This is possible when using a lever system with the rake, where the input force is applied over a shorter distance but results in a greater output force over a longer distance. The mechanical advantage gained from the lever system allows for the output force to be greater than the input force in this scenario.
