SUMMARY

The discussion focuses on the mechanics of fidget spinners on sloped surfaces, emphasizing the role of radial arms and weights in altering rotation rates. It highlights the principle of conservation of angular momentum, where moving weights inward increases rotation speed, while releasing weights outward decreases it. Participants explore potential applications for this mechanism, suggesting its integration into machines for enhanced functionality.

PREREQUISITES
  • Understanding of angular momentum principles
  • Familiarity with mechanical systems and their components
  • Basic knowledge of rotational dynamics
  • Experience with fidget spinner mechanics
NEXT STEPS
  • Research the physics of angular momentum in rotating systems
  • Explore applications of fidget spinner mechanics in engineering
  • Learn about the design of mechanical governors
  • Investigate advanced rotational dynamics simulations
USEFUL FOR

Engineers, physics students, hobbyists interested in mechanical design, and anyone exploring the practical applications of rotational dynamics.

Homework Statement
So I have a project to construct a rube goldberg machine, and one of the required physics concepts that needs to be shown in the maxine is conservation of angular momentum. So far all I could come up with is like flipping a water bottle or spinning a fidget spinner then tilting the surface but both of those are hard to incorporate into my machine. Do you guys have any other ideas?

Something that rotates has radial arms with weights that can be moved along the arms. String through the hub goes out to the weights and pulls them inward (as the string wraps around the axle or something). As the weights move inward the rate of rotation increases impressively due to conservation of angular momentum. Or the opposite, something spinning fast has weights released to move outward slowing the rate of rotation.

Do you know what this is used for? It could be a nice addition to your machine...
