A lever is a simple machine that uses a bar on a fixed point to lift heavy objects with ease. The fulcrum is where the two pieces meet and effort and load are applied on opposite sides. A door handle is an example lever.
A pulley is a wheel with a grooved rim that a rope or chain runs through to change the direction of a pull and lift loads. Examples are shoe laces and window blinds.
An inclined plane is a ramp that raises an object to a higher level, making it easier to move. Examples are wheelchair ramps and stairs.
A wheel and axle uses an axle on which a wheel is attached to pull a rope or chain and move
![Lever ,[object Object],The fulcrum is located where the two pieces meet and the effort is you and the load is the sharp part. A door handle is a lever because the fulcrum is located where the door and the handle meet and when you applied effort to the handle it lifts the load on the inside of the door which causes the door to open.](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
