Getting in Gear

Submitted by Randy Steele on 15 July, 2011 - 10:40
Overview: 
The goal of this lesson is to explore the use of gears to tradeoff between speed and power(torque) in a robot design. Students learn about gearing up, gearing down and calculating gear ratios. There is also an extended lesson on compound gear ratios for advanced students.
Objectives: 

Student will be able to:

1. Explain the behavior of a two-gear gear train

2. Calculate the gear ratio of a two-gear gear train

3. Describe gearing-up and gearing-down in terms of speed and power
