what is a simple machine
What is a Simple Machine?
  • A simple machine has few or no moving parts.
  • Simple machines make work easier.
  • Scientists have identified six different simple machines: lever, screw, pulley, wedge, inclined plane, and wheel and axle.
wheels and axles
Wheels and Axles
  • The wheel and axle together form a simple machine.
  • The axle is a rod that goes through the wheel allowing the wheel to turn.
  • Gears are a form of wheels and axles.
pulleys
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
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
Wedges
  • A wedge consists of two inclined planes joined back to back.
  • Wedges are used to split or cut things.
screws
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
Levers-First Class
  • In a first class lever the fulcrum is in the middle and the load and effort is on either side.
  • A see-saw is a good example of a first class lever.
levers second class
Levers-Second Class
  • In a second class lever the fulcrum is at the end, with the load in the middle.
  • A wheelbarrow is a good example of second class lever.
levers third class
Levers-Third Class
  • In a third class lever the fulcrum is again at the end, but the effort is in the middle.
  • A pair of tweezers is a good example of a third class lever.

Simple Machines

Simple Machines can be put together in different ways to make complex machinery.
