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...
