Gears By: Student Name Class: 8D Date: April, 30, 2003

A Gear is a rotating wheel-like device with teeth around the rim. The teeth of each gear connect with each other causing other gears to rotate. Definition

Gears are used a lot in everyday life. Some examples of using the gears would be bicycles, different machines in factories and tractors. Everyday Use

Mechanical Advantage MA=Radius of effort load Radius of a load gear

On a bike the radius of the effort gear is 30cm and the radius of the load gear is 5 cm what is the mechanical advantage???? MA Problem

The mechanical advantage is is 6. Solution
