A simple machine is a machine with few or no moving parts. Simple machines make work easier.
There are six simple machines Screw Wheel and Axle Wedge Pulley Inclined Plane Lever.
3 Inclined Plane
A sloping surface such as a ramp. An inclined plane can be used to alter the effort and distance involved in doing work such as lifting loads. The trade-off is that an object must be moved a longer distance than if it was lifted straight up but less force is needed.Examples Staircase Ramp Bottom of a Bath Tub
A straight rod or board that pivots on a point known as a fulcrum. The fulcrum can be moved depending on the weight of the object to be lifted or the force you wish to exert. Pushing down on one end of a lever results in the upward motion of the opposite end of the fulcrum.Examples Door on Hinges Seesaw Hammer Bottle Opener
A wheel that usually has a groove around the outside edge. This groove is for a rope or belt to move around the pulley. Pulling down on the rope can lift an object attached to the rope. Work is made easier because pulling down on the rope is made easier due to gravity. Examples Flag Pole Crane Mini-Blinds
An inclined plane wrapped around a shaft or cylinder. This inclined plane allows the screw to move itself or to move an object or material surrounding it when rotated. Examples Bolt Spiral Staircase
Two inclined planes joined back to back. Wedges are used to split things.Examples Axe Zipper Knife
8 Wheel and Axle
A wheel and axle has a larger wheel (or wheels) connected by a smaller cylinder (axle) and is fastened to the wheel so that they turn together. When the axle is turned the wheel moves a greater distance than the axle but less force is needed to move it. The axle moves a shorter distance but it takes greater force to move it.Examples Door Knob Wagon Toy Car
