Mechanics - Rigid Bodies, Forces, Motion | Britannica
A body is formally regarded as rigid if the distance between any set of two points in it is always constant. In reality no body is perfectly rigid. When equal and opposite forces are applied to a body, it is always deformed slightly.

A rigid body is an idealization of a solid body where the deformations occurring on the body are neglected. In other words, the distance between any two given points of a rigid body remains constant regardless of the external force acting upon it.
In this section, we determine how to calculate the angular momentum and kinetic energy of a rigid body, and define two important quantities: (1) the center of mass of a rigid body (which you already know), and (2) the Inertia tensor (matrix) of a. rigid body.
EN4 Notes: Kinematics of Rigid Bodies - Brown University
A rigid body is an idealization of a body that does not deform or change shape. Formally it is defined as a collection of particles with the property that the distance between particles remains unchanged during the course of motions of the body.
Rigid Body Dynamics | Principles, Motion Analysis & Forces
2024年5月27日 · Unlike particles, rigid bodies have dimensions and shapes, and their motion involves translation and rotation. This article delves into the core principles of rigid body dynamics, exploring the key concepts that govern motion analysis and force interaction in rigid bodies.
21.1: Introduction to Rigid Body Dynamics - Physics LibreTexts
2020年12月30日 · We shall analyze the motion of systems of particles and rigid bodies that are undergoing translational and rotational motion about a fixed direction. Because the body is tran slating, the axis of rotation is no longer fixed in space.
A rigid body is a system of particles with fixed locations relative to each other. An ordinary solid object is approximately a rigid body, although the particles actually oscillate in thermal motion about their equilibrium positions, and they can be displaced slightly from those positions by external forces.
13.1 Rigid Bodies. rigid body consists of a group of particles whose separations are all fixed in magnitude. Six independent coordinates are required to completely specify the position and orientation of a rigid body. For example, the location of the first particle is specified by three coordinates. A second particle requires only two ...
Since the distances between any two other points are xed in the rigid body, any other point of the body is fully determined by the distance to these 3 points. The translations of the body require three spatial coordinates. These translations can be taken from any xed point in the body.
What Is A Rigid Body? – Physics Notebook
A rigid body is a system of particles (an assembly of a large number of particles), in which the distance of the inter-particle remains unchanged when it is acted upon by an external force or torque.
