Discussion Overview

The discussion revolves around the theoretical maximum RPM at which a circular sheet of graphene with a radius of 1 meter can spin without tearing apart. The scope includes theoretical considerations related to material properties and mechanical stress.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant inquires about the maximum RPM for a 1 m radius graphene sheet before it fails structurally.
  • Another participant suggests that the question may stem from a science fiction context, questioning the intent behind the inquiry.
  • A different participant expresses that the question is a product of creative thinking during summer boredom, not related to writing fiction.
  • One participant recommends consulting Roark's Formulas for Stress and Strain for relevant equations and emphasizes the need for mechanical properties of graphene to perform the calculations.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the theoretical maximum RPM, and the discussion includes varying perspectives on the nature of the inquiry.

Contextual Notes

The discussion lacks specific mechanical properties of graphene and does not detail the assumptions necessary for calculating the maximum RPM.

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.
