| Abstract: | A new experimental method and system is used to measure the moment of inertia.The effect of string pull impacting on the friction torque of spindle is considered by adding a standard rigid body test piece in the physical experiment measuring the moment of inertia of a rigid body,which has improved the accuracy of this experiment greatly.In addition,the time data being measured by single MCU are transported to a personal computer by means of the communication network,which is according to PLT communication a... |
