Explains how a wedge works, the formula for calculating its mechanical advantage, and some common applications of wedges.

This site from Dirtmeister gives information on how the Ancient Egyptians used the inclined plane. Dirtmeister explains the inclined plane and its uses.

Scholastic provides an in-depth explanation to a simple-machine concept here as The Wedge. Also provides a picture and several examples for understanding.

Learn about the different types of simple machines.

Here is a simulation demonstrating an object placed on an inclined plane. The user will vary the slope of the plane to see the relationship the slope has on the gravity of the object and the static friction.

A thorough discussion of all the simple machines, beginning with some thoughts on mechanical advantage and conservation of energy. Very complete. Move down to the section that interests you.

Gives short descriptions of the six types of simple machines.

Designed for Grade Eight, this collection of lessons provides information, examples and quizzes related to simple machines. Elementary students studying this topic will find this site informative as well.

Simple machines such as inclined planes in wedges and screws are explained.

Scholastic provides an in-depth description here of a simple machine called The Screw. Also provides a picture and several examples for understanding.

This site provides a chart that lists the six simple machines, defines them, explains how it helps and gives examples.

A full and complete discussion of the simple machine called the screw, a modified inclined plane. Many examples and drawings and applications.
