  2. Inclined Plane • An inclined plane is a flat surface that is higher on one end. You can use this machine to move an object to a lower or higher place. • Inclined planes make the work of moving things easier. You would need less energy and force to move objects with an inclined plane. • The longer the slope of the inclined plane the easier it is to pull or push the heavy object up or down the inclined plane. Examples: • Ramp • Slanted Road • Path up a Hill • Slide

  3. A lever is a board or bar that rests on a turning point. This turning point is called the fulcrum. • An object that a lever moves is called the load. The closer the object is to the fulcrum, the easier it is to move. Lever • There are many different kinds of levers. One of them is like a see-saw. There is a load on one end, and when the person pushes one end down the load on the other side will move. Hammer Examples: Crow bar • A hammer is a lever when it is used to • pull a nail out of a piece of wood. • Crow bars • Bottle openers • Seesaw

  4. Wedge • A wedge is a simple machine used to push two objects apart. • A wedge is made up of two inclined planes. These planes meet and form a sharp edge. This edge can split things apart. Examples: • Axes • Knives • Nails • Door stopper

  5. Screw • A screw is a simple machine that is made from another simple machine. It is actually an inclined plane that winds around itself. • A screw has ridges and is not smooth like a nail. • Some screws are used to lower and raise things. They are also used to hold objects together. Examples: • Spiral Staircase • Jar Lids • Wrenches • Key Rings • Clamps • Stools • Light Bulbs

  6. Pulley • This simple machine is made up of a wheel and a rope. The rope fits on the groove of the wheel. One part of the rope is attached to the load. • When you pull on one side of the pulley, the wheel turns and the load will move. • Pulleys let you move loads up, down, or sideways. Pulleys are good for moving objects to hard to reach places. It also makes the work of moving heavy loads a lot easier. Examples: • Flag Poles • Crane • Clothes Lines • Sailboat • Window Blinds

  7. Wheel and Axle • The wheel and axle is another simple machine. The axle is a rod that goes through the wheel. This lets the wheel turn. It is easy to move things from place to place with wheels and axles. Examples: • Cars • Door Knobs • Roller Skates • Wagons & Wheelbarrows • Gears in Watches, Clocks, and Bicycles
