The lever is one of the most basic forms of a machine. They help us lift loads with lesser effort. Even though this looks simple there are many things going on in order to lift the object easily.
A lever can be described as a long rigid body with a fulcrum along its length. It is used for lifting objects.
Load : The object you’re lifting.
Fulcrum : Point at which the lever pivots.
Effort: The force applied to make the object move.
