摘要
以刚体的平衡方程为理论依据推断出刚体在各种运动状态下能否处于平衡状态,并导出处于平衡状态所满足的运动学条件;同时对刚体在平面力系作用下平衡条件的等价条件作了证明。
This paper mainly discusses equilibrium of Rigid body in different motions, based on equilibrium equation of Rigid body so as to deduce whether Rigid body can be in a state of equilibrium and its Kinematics condition ,and proves the equal equation of Rigid body under Plane forces interracted.
