  1. SIMPLE MACHINES • BymONTSEBermúdez

  2. The Inclined Plane • The inclined plane is the simplest of simple machines because to • make it work, nothing moves. • You move! Another name for an inclined plane is a ramp. • Examples: Staircase, Ramp, Bottom of a Bath Tub

  3. SimpleMachine: • A machine withfewor no movingparts. Simple machines makeworkeasier.Examples: Screw, Wheel and Axle, Wedge, Pulley, InclinedPlane, Lever

  4. Compound Machine Twoor more simple machines workingtogethertomakeworkeasier. Examples:Wheelbarrow, Can Opener, Bicycle

  5. The Wedge A wedge is really an inclined plane turned on its side. But instead of helping you move things to a higher level, a wedge helps you push things apart. The blades of a knife or a shovel are both wedges. A wedge can also be round, like the tip of a nail, or the tines on your fork. Examples: Axe, Zipper, Knife

  6. TheScrew • Thescrewisreallyaninclinedplane in the round with a wedge at the • tip. Think of a typicalscrew. Thewedgeisthepointedend. Theinclined • planeisthethreadthatwrapsaroundthescrew. Screwsare usedin • manydifferent places toholdthingstogether. • Examples: Bolt, SpiralStaircase

  7. The Lever In its simplest form, a lever is a stick that is free to pivot or move back and forth at a certain point. Levers are probably the most common simple machine because just about anything that has a handle on it has a lever attached. The point on which the lever moves is called the fulcrum. By changing the position of the fulcrum, you can gain extra power with less effort. A good example of a lever is a see-saw. Examples: Door on Hinges, Seesaw, Hammer, Bottle Opener

  8. The Wheel and Axle A wheel and axle is really two machines in one because you can use each part in different ways. The first way is to roll something along. Wheels help you move an object across the ground because they cut down on the amount of friction between what you're trying to move and the surface you're pulling it against. (The axle is the object that attaches the wheel to the object it's moving.) Examples: Door Knob, Wagon, Toy Car

  9. ThePulley The pulley is really a wheel and axle with a rope or chain attached. A pulley makes work seem easier because it changes the direction of motion to work with gravity. Examples: Flag Pole, Crane, Mini-Blinds

  10. Gears Two toothed wheels fit together either directly or through a chain or belt so one wheel will turn the other. Some gears may have a screw or a toothed shaft in place of one of the wheels. A gear may also be a combination of toothed wheels that produces a certain speed (such as a bicycle's top gear which makes the bike go fast, and the low gear for slow speed.)Examples: Clock, Automobile, Drill

  11. As always, thankyou.
