1. SIMPLE MACHINES
A swift and easy way for you to learn all about the 6 simple machines!!!

2. What is a Simple Machine?
A simple machine is a machine with few or no moving parts.
Simple machines help us by making work easier.
Ex: Pulley, Wedge, Inclined Plane, Screw, & Wheel and Axle.

3. Mechanical Advantage
A mechanical advantage is the rate of the output force\work to the input force\work.
The mechanical advantage of a machine can be found using this equation:
MA : Output force (N)\Input force (N)

4. Inclined Plane An inclined pane is a sloping surface.
Inclined planes help us by lifting large loads.
Ex: A ramp
IMA= length of slope (m)\height of slope (m)

5. Wedge A wedge is two inclined planes joined back to back.
Wedges are used to split things.
Ex: Axe or Knife

6. Pulley
A pulley is a wheel that normally has a groove around the outside edge. (The groove is for a rope or belt to move around the wheel.)
Ex: Flag Pole

7. Screw A screw is an inclined plane wrapped around a shaft or cylinder.
Ex: Jar lid and A bolt

8. Wheel and Axle
A wheel and axle is a large wheel connected to a cylinder (axle) so that they rotate together.
Ex: A doorknob and a combination lock
IMA= Radius of wheel (m)\ Radius of axle (m)

9. Levers A lever is a bar that is free to pivot\turn around a point.
There are 3 types of levers: First-Class Levers, Second-Class Levers, and Third-Class Levers.
Ex: Seesaw
IMA= Length of input arm (m)\ Length of output arm (m)
