刚体平衡条件之讨论

The Discussion on the Balanced Condition of Rigil Body

刚体平衡条件即刚体的静平衡条件和刚体的动平衡条件。文章在刚体的静平衡条件中主要讨论刚体在外力作用下处于静止状态下的平衡,在动平衡条件中着重讨论刚体以定轴转动的平衡,从中总结刚体的平衡条件。

The balanced condition of rigil body includes its static equilibrium condition and dynamic equitibrium condition About the static equilibrium of rigil body, we mainly discuss the balance of rigil body which is static under the external forces, For its dynamic equilibrium,we talk about The balance when the fixed axle turns the rigil body, then sum up the balanced condition of tigil bodies.
