SUMMARY

The maximum theoretical RPM for a circular sheet of graphene with a radius of 1 meter can be calculated using principles from mechanics and material science. The key resource for this calculation is Roark's Formulas for Stress and Strain, specifically the Fifth Edition, which provides the necessary equations. Understanding the mechanical properties of graphene is crucial for accurate calculations, as these properties directly influence the material's ability to withstand high rotational speeds without tearing.

PREREQUISITES
  • Understanding of mechanical properties of materials
  • Familiarity with Roark's Formulas for Stress and Strain
  • Basic knowledge of rotational dynamics
  • Ability to perform stress and strain calculations
NEXT STEPS
  • Research the mechanical properties of graphene
  • Study rotational dynamics and its applications in material science
  • Explore advanced stress analysis techniques using Roark's Formulas
  • Investigate real-world applications of high-speed spinning materials
USEFUL FOR

Material scientists, mechanical engineers, and anyone interested in the theoretical limits of material performance under rotational stress.

Theoretically, how fast in RPM can a circular sheet of graphene of radius 1 m spin without tearing apart?

It sounds like you might be writing a SF story. Is that correct?
 
No, I just had a wild idea that involves spinning something really fast. Bored to death during summer vacations causes my mind to run wild.

If you like to amuse yourself with these type of questions, you might invest in a copy of Roark's Formulas for Stress and Strain. You don't need the latest edition, the Fifth Edition has exactly the equation you need. You also need the mechanical properties of the material to do the calculation.
