SUMMARY

The discussion focuses on replicating the rocking semi-cylinder problem from analytic mechanics. The user seeks a source for purchasing a solid semi-cylinder, suggesting contacting machine shops that specialize in shaft work. Precision tolerances are crucial for this project, and the user recommends searching for "half round bar" materials. A specific resource mentioned is McMaster-Carr, which offers half-round bars suitable for this application.

PREREQUISITES
  • Understanding of analytic mechanics principles
  • Familiarity with precision machining and tolerances
  • Knowledge of materials used in mechanical applications
  • Experience with sourcing industrial materials
NEXT STEPS
  • Research precision machining techniques for custom semi-cylinder fabrication
  • Explore McMaster-Carr's catalog for half-round bar options
  • Investigate local machine shops that offer shaft work services
  • Learn about tolerances and their impact on mechanical performance
USEFUL FOR

Mechanical engineers, physics students, and hobbyists interested in replicating mechanical systems or conducting experiments in analytic mechanics.

TL;DR
I'm unsure where I might find such an object for the precision I'm looking for. Ideally, it'd come with known dimensions (density, mass, length-dimensions, etc).
I want to replicate the rocking semi-cylinder problem from analytic mechanics, but don't actually have in my possession a nice, solid cylinder to rock. I imagine my professor likely made his, or found it somewhere in Estonia. If anyone can point me to place where I might be able to find one for purchase, that would be nice.

I would suggest contacting a machine shop that does shaft work. They should have precision shaft material that can be cut to length and split. The key will be what tolerances you can work with.

Search for "half round bar". For example, https://www.mcmaster.com/half-rounds
You might have success finding something off-the-shelf depending on dimensions and precision required.
