| Abstract: | This paper analysised the source of error of the experiment of experimental instrument of the rigid body moment of inertia and pointed out the main factors causing errors is disaccurate time measurement and moment of resistance.We measured moment of resistance and quantitative analysised of the influence of the moment of resistance.When the mass is 20g,the ratio of moment of resistance and tension moment of weight is up to 19%. |
