methods according to vibration theory the relationship between the period of a torsional pendulum and the moment of inertia of a part is established and the test method is given.
根据振动理论建立了零部件单摆振动周期和转动惯量的关系,给出了实际测量方法。
the torsional pendulum experiment is set up in order to extend the curricula of experiments of nonlinear system.
