Simple machines are what people use to make work easyer.
The simple machines are the lever, wedge, pully, inclined plane, screw, wheel and axel.
The lever is a wedge that holds up a bar to lift up objects.
The wedge is two inclined planes that goes in something like a rock and use a hammer to brake it open.
The pully is a rope on a tree and theres a board attached to the rope and people pull the other side and it lifts the object up.
The inclined plane is a wedge you can walk over.
The screw is used to hold up objects.
The wheel and axel is used to push objects along.
These simple machines are useful to get work done.
