@gash50175 months ago Which rotating speed and which critical speeds can you explain.
@

@arivan3293 years ago Thank you for this excellent video. Noticed that at - , the explanation requires a minor correction. The rotor on the left hand side is flexible rotor while right hand side is rigid rotor. .. ...Expand 1
