| Abstract: | Rotating table for centripetal force investigation with control variate method was designed.This device adopted frequency-conversion power source to drive synchronous motor to achieve uniform rotation,and it was easy to adjust and record speed without electromagnetic or photovoltaic switch.This device used electronic scale instead of spring or tension sensor,rotating table instead of transom,and thrust ball bearing,which made the device have a good stability and loading capacity.This device could also be us... |
