What is a Simple Machine? A simple machine has few or no moving parts. Simple machines make work easier
Wheels and Axles The wheel and axle are a simple machine The axle is a rod that goes through the wheel which allows the wheel to turn Gears are a form of wheels and axles
Pulleys Pulley are wheels and axles with a groove around the outside A pulley needs a rope, chain or belt around the groove to make it do work
Inclined Planes An inclined plane is a flat surface that is higher on one end Inclined planes make the work of moving things easier
Wedges Two inclined planes joined back to back. Wedges are used to split things.
Screws A screw is an inclined plane wrapped around a shaft or cylinder. The inclined plane allows the screw to move itself when rotated.
Levers-First Class In a first class lever the fulcrum is in the middle and the load and effort is on either side Think of a see-saw
Levers-Second Class In a second class lever the fulcrum is at the end, with the load in the middle Think of a wheelbarrow
Levers-Third Class In a third class lever the fulcrum is again at the end, but the effort is in the middle Think of a pair of tweezers
Simple Machines Simple Machines can be put together in different ways to make complex machinery
