In physics, a rigid body, also known as a rigid object, [2] is a solid body in which deformation is zero or negligible, when a deforming pressure or deforming force is applied on it. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it.

2023年5月19日 · In physics, a rigid body (also known as a rigid object) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it.

2023年5月11日 · Answer: A rigid body (also known as a rigid object) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it.

2025年1月23日 · Rigidity is a physical property of solids that describes its ability to resist change in shape when an external force is applied. Rigidity, as a mechanical property of matter, refers to the resistance of a material to deformation, particularly bending, shearing, or compression.

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 …

In physics, a rigid body, also known as a rigid object, is a solid body in which deformation is zero or negligible, when a deforming pressure or deforming force is applied on it. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it.

Fortunately, it is easily shown for a rigid body that, if the net force is zero and the net torque is zero with respect to any one point, then the net torque is also zero with respect to any other point in the frame of reference. A body is formally regarded as rigid if the distance between any set of two points in it is always constant.

A rigid body is an idealized solid object in which the distances between any two points remain constant regardless of external forces or moments applied to it. This concept simplifies the analysis of motion and forces, as it assumes that the body does not deform under stress, allowing for straightforward calculations of angular momentum and ...

A rigid body is an idealized solid object where the distance between any two points within it remains constant, no matter what external forces or torques are applied. This means that the body does not deform or bend—it stays the same shape.

In this chapter we will consider the motion of solid objects under the application of forces and torques. We call these solid objects ``Rigid Bodies''. Of course nothing is completely rigid. Objects deform elastically, but these deformation are negligible for a wide range of problems.
