Simple Machines By Greg Corder

Table of Contents Work Levers (1 st, 2 nd, and 3 rd Class) Inclined Plane Screw and Wedge Pulleys Wheel and Axle Sources

Work = Force X Distance Simple machines conserve work! That means that you get back the same work from the machine that you put in. For example, Work = Force X Distance

In other words:

The 6 Simple Machines!

1 st Class Lever See-saw, crowbar, etc

2 nd Class Lever Wheelbarrow, door, etc.

3 rd Class Lever Fishing pole, broom, bat, golf club, etc.

Inclined Plane Ramp, Stairs, etc.

Wedge and Screw Doorstop, nail, chisel, etc. Corkscrew, nut/bolt, etc.

Pulleys Elevator, flagpole, etc.

Wheel and Axle Doorknob, screwdriver, pencil sharpener
