Discussion on Teaching of the Perpendicular Axis Theorem of the Moment of Inertia of a Rigid Body; reverse idler gear shaft bearing 刚体转动惯量正交轴定理的教学探讨
Otherwise the perpendicular axis theorem doesn't work. 否则垂直轴定理不能应用。
General form of perpendicular axis theorem 垂直轴定理的一般形式
With teaching practice, we put forward some advice in the teaching how to use the perpendicular axis theorem to find the moment of inertia of a rigid body, which could enrich teaching context and expand students 'knowledge. 结合教学实践,提出对刚体转动惯量正交轴定理的教学,着重介绍一般推广式,继而得出相关引伸式.使教学内容更加丰富,并拓宽知识面。
