Correct Answer 1, 2 and 3 only
A critical speed of a rotating shaft is the speed at which the shaft starts to vibrate violently in the transverse direction. Critical speed of shaft is also called whirling speed or whipping speed of shaft. The whirling of the shaft results from mass unbalance of the rotating system. The environment has no effect on whirling speed of shaft.
