摘要: 讨论了杆摆运动中的切向内力及其力矩、法向内力及其力矩;计算了内力及内力矩所作的功.这对进一步理解“质点”、“刚体”等概念有一定的参考价值.

关键词: 杆摆, 内力, 内力矩,

Abstract: The tangential in,ternal force and its moment and the normal internal force and its moment in a moving rod pendulum are discussed. The work done by the internal forces and the moment Of internal forces are calculated. The discussion might be meaningful for correctly understanding some physical models like particle and rigid body.

Key words: rod pendulum, internal force, moment of internal force, work
