B Spinning graphene

  1. Aug 9, 2018 #1
    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.
