### How can I calculate rotational speed? Example

Aug 03, 2018 0183 32 Hope it helps, Rotational speed omega can be evaluated considering the change in angular displacement theta with time t omega=theta/t Practically this can be a bit dfficult so what we do to measure the rotational speed of, say, a motor shaft is to visually count the number of rotations per minute We observe a point on the rim of the rotating shaft and we count the number of rotations say ....

### critical rotational speed for ball milling

Critical speed In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gearAs the speed of rotation approaches the object s natural frequency, the object begins to resonate, which dramatically increases system vibration...
