Question

What are the characteristics of a rigid body?

Answer 1

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. A rigid body is usually considered as a continuous distribution of mass.

   1. All lines on a rigid body have the same angular velocity and the same angular acceleration.

   2. Rigid motion can be decomposed into the translation of an arbitrary point, followed by a rotation about the point.

Answer 2

The characteristics of a rigid body

As we know that 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. A rigid body is usually considered as a continuous distribution of mass.

1. All lines on a rigid body have the same angular velocity and the same angular acceleration.

2. Rigid motion can be decomposed into the translation of an arbitrary point, followed by a rotation about the point.
