Gears- compare efficiencies, effect of different lubricants
Gears are among the most efficient and the most reliable methods for transmitting rotary motion and force. Gears are used in watches, clocks, cars, toys, and millions of other industrial and household equipments.  Gears are strong, durable and reliable. In this project we will test the efficiency of a gear system and test the effect of lubricants on a gears efficiency.
 Project description
In this project you will use a gear system (or build one) in order to test it's efficiency before and after lubrication.
