Gearing

  • Below is a picture of a Gear System, build it using the Wackano set.
  • Discuss how the gear system changes the direction of each gear in the system.
  • Calculate the ratios of each gear in the system.

  • Be creative and design your own gear system.
  • Now calculate out the gear ratios of each gear.

Challenge

  • Using the skills you have learned from building the Wackano mechanisms. Design a system which has an object moving in each of the far corners of the board. All the objects must move from one point.
