3.2 Mechanical Gears (Mechanisms)
What do a guitar, a bicycle, an eggbeater, and a sewing machine have in common? They all use gears to increase, decrease, or redirect power. Gears come in all sizes. A mechanical wind-up watch has very small gears, while the gears used to lift a bridge to allow ships to pass underneath are huge. Different gear configurations are used for different purposes.
In this activity you and your classmates will build gear assemblies and observe how they are used. This information will come in handy when your class designs and builds an automated factory assembly line.
