How does a lever help people?
There are 3 classes of levers. You can use them to increase the output force, thus allowing a person to lift something much heavier than they could without the lever. It can also be used to increase speed, and or change the direction of the applied force. You can't pull a nail out of a board with your hands, but a crowbar can be used to do so.

What has a pivot point between a load and an input force?
The answer is: a lever.A lever is a simple machine that has a stick that pivots at a point called a Fulcrum.There are 3 types of Lever:First class lever: A first class lever is when a fulcrum is in the middle of the input force and the load. An example is a seesaw in the playground. When you press down the side of seesaw,(input force) the other side goes up. (load, output force) In the middle, there is a fixed point.Second class lever: A second class lever is where you have the load in the middle of the Fulcrum and the input force. An example would be a wheelbarrow. The basket in the middle is the load( also called the output force) the wheel at the end is the Fulcrum, and the handle that you press up and down is the input force.Third class lever: A third class lever is a lever that has a input force in between the Fulcrum and the Load. An example is a Hammer. The sharp part is the load(output force) the part you grab and swing is the input force, and the other end of the hammer is the Fulcrum.

Class 1 lever
Why can a clothespin be a class 1 lever and a class 3 lever?
because In a Type 1 Lever, the pivot (fulcrum) is between the effort and the load. In an off-center type one lever (like a pliers), the load is larger than the effort, but is moved through a smaller distance. Examples of common tools (and other items) that use a type 1 lever include and in a Type 3 Lever, the effort is between the pivot (fulcrum) and the load.
