Simple machines are tools that help move an object.
There are 6 different machines for example: Pully, axel and wheel, inclined plane, wegde, screw and lever.
The pully lifts up heavy weight.
The axel and wheel helps transport different materials.
The incline plane helps people go up without them using the stairs while they're holding lots of stuff.
The wedge helps people cut objects in half.
The screw helps hold two materials.
The lever helps us move something thats heavy.
These 6 machine are still used today to move objects.
