摘要
证明了有一类均质刚体的转动惯量可以用少数几个质点做代表进行计算,并给出了计算的通式,从而可以不用积分就能计算出其转动惯量.提出了不用积分法推出刚体转动惯量计算公式的新方法.
Proves that the rorational inertia of some uniformed bodies can be calculated with several particles, and gives out general formula for calculation, the rorational inertia of some uniformed bodies is obtained without doing integral, then proposes new method to calculate the rorational inertia of some uniformed bodies.
