| Abstract: | By means of the analysis on motion equation of simple pendulum, a method for testing the moment of inertia of a complex shaped rigid-body moving around a fixed axle under the condition of not knowing the barycentric position of the object was obtained. Finally an analysis was made on the errorsbeing tested and an effective method for reducing the tested errors has been put forward. |
