Critical speed — Fixed at one end and supported at the other, distributed mass
Critical speed of a shaft fixed at one end and supported at the other. The mass of the shaft itself is treated as distributed along its length, so enter the total mass of the shaft. The critical speed falls between the simply supported and the fixed-at-both-ends cases.
