The dynamics of rigid bodies is a fascinating and complicated subject . 刚体动力学是一个诱人而复杂的论题。
Mechanics is the study of the motion of collections of rigid bodies under given forces . 力学是研究刚体集合在力作用下的运动。
This increases both the rigid body rotation of the vehicle and the bending moment . 这既增加了飞行器的刚体转动,也增加了弯矩。
For a rigid body rotating about a principal axis, the angular acceleration is related to torque by t =ia . 对于绕主轴转动的刚体来说,角加速度与转矩的关系是TIa。
The discussion has served to emphasize the important role the inertia tensor plays in the discussion of the motion of rigid bodies . 讨论强调了惯性张量在论述刚体运动时所起的重要作用。
In physics, a rigid body is an idealization of a solid body in which deformation is neglected. In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.
