Abstract:This paper introduced a new three-line pendulum system and method to measure moment of inertia.In this system，sensors and data collecting equipment were used to collect periodic signal and force signal，while special software was developed to calculate the moment of inertia.This method combined mechanical equipment with electronic and computer.Compared with existing method，this one avoids manual operation and calculation and is practical and convenient.It can be used to measure good-sized rigid body.The whole process tends to be automatic with improvement in precision and efficiency.
