SUMMARY

The discussion focuses on calculating the force exerted on a 16cm diameter rigid wheel as it travels over a bump. Key factors influencing this force include the wheel's velocity and the bump's shape. Participants suggest that while computer simulation programs can provide precise calculations, approximations can be made by analyzing the bump's shape and peak. Tools like free simulation software are recommended for those seeking a more detailed analysis.

PREREQUISITES
  • Understanding of basic physics principles related to force and motion
  • Familiarity with wheel dynamics and their interaction with surfaces
  • Knowledge of computer simulation tools for physics modeling
  • Ability to approximate geometric shapes and their effects on force
NEXT STEPS
  • Research free computer simulation software for physics, such as Algodoo or PhET
  • Study the principles of force calculation in rigid body dynamics
  • Explore methods for approximating bump shapes and their impact on force
  • Learn about the relationship between velocity and force in mechanical systems
USEFUL FOR

Mechanical engineers, physics students, and hobbyists interested in vehicle dynamics and force analysis on wheels.

I need to approximate how much force is exerted on a 16cm diameter wheel (assume it's rigid and doesn't absorb force) upon traveling over an average sized bump (relative to its diameter).

Does anyone have a suggestion on a method to do this?
 
Physics news on Phys.org
I would say that it depends entirely on the velocity and shape the bump. The force exerted on the wheel will continue to change as the wheel moves over the bump. Where the max occurs and how much this max is depend on situation. Sounds like something computer simulation programs would be useful for.
 
Is there any approximation I can make at all without using computer simulation (unless it's easy to use and free to download)? What if I approximated the shape and peak of the bump as well?
