Product Details

We are surrounded by gears. They are in our cars, clocks, dishwashers, saws and most other common mechanical devices. What do gears do? Why are they used? What are their advantages? Discover the answers to these questions and more with the hands-on activities and working gearbox in this kit. Students will experiment with various gear arrangements and discover directional and speed relationships resulting from different gear combinations. Quantitative data will be collected on various gear ratios and students will derive the torque values and mechanical advantage of the specific combinations. You will definitely want to include this involving gear kit as a part of your simple machines curriculum.

Complete for one student group. Super Value Kit is complete for 8 student groups.
