Marble loop roller coaster launcher

Click For Summary
SUMMARY

The discussion focuses on designing a marble loop roller coaster launcher that utilizes elastic potential energy to successfully navigate a vertical loop and achieve projectile motion. Participants suggest alternatives to compression springs, specifically considering elastic bands as a viable option. The goal is to ensure consistent launching of the marble to a specified location, emphasizing the importance of energy transfer and launch mechanics in the design process.

PREREQUISITES
  • Understanding of elastic potential energy principles
  • Familiarity with projectile motion concepts
  • Basic knowledge of mechanical design and physics
  • Experience with materials like springs and elastic bands
NEXT STEPS
  • Research the mechanics of elastic potential energy in launching systems
  • Explore the physics of projectile motion to optimize launch angles
  • Investigate design techniques for consistent marble launching
  • Experiment with different materials for energy storage, such as various elastic bands
USEFUL FOR

Students, hobbyists, and engineers interested in physics-based design, particularly those working on mechanical projects involving energy transfer and motion dynamics.

Help me here.

I need to figure out how to launch a marble so it navigates a vertical loop, then follows projectile motion at the end of the loop

The design must use elastic potential energy to do this and must consistantly launch it consistantly to a specifyied location.

I can't figure out how to launch the marble..

Any ideas other than a compression spring??

Seems like you have a choice between spring and elastic band.
