In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating...

eigenfrequencies as a function of the shaft's rotation speed. This case is also called "whirl speed map". Such a chart can be used in turbine design. Experimentally...

swaying is damped out below a critical speed, but is amplified by the forward motion of the train above the critical speed. This lateral swaying is known...

applications simply due to gravity). The Froude number is based on the speed–length ratio which he defined as: F r = u g L {\displaystyle \mathrm {Fr}...

running speed for a leadscrew (or ball screw) is typically limited to, at most, 80% of the calculated critical speed. The critical speed is the speed that...
