How do I determine the theoretical burst speed of a rotating disk, such as a flywheel? I went through my physics textbooks from 30 years ago with no luck. I googled, and found WAY too much information, but still no equation.(adsbygoogle = window.adsbygoogle || []).push({});

Is this similar to the formula for hoop stress in a pressure vessel, only using centrifugal force instead of gas pressure?

Could I figure that the entire mass was at the radius of gyration?

I'm not sure how to determine the stress distribution.

I've been out of school for 3 decades now and I'm not as sharp at integral calculus as I used to be...

Thank you,

Michael
