Classical Mechanics - Rigid Body Mechanics : Degree of Freedom and Generalized Coordinates

This is the first video on Mechanics of a Rigid Body. Concepts of the generalized coordinates and the degree of freedom of a rigid body have been discussed here. A system of particles in which the distance between any two particles remains fixed throughout the motion. The rigid body has six degrees of freedom and therefore we need six generalized coordinates or independent variables to describe the motion of a rigid body. This fact has been explained in detail by two methods. Another feature of this video is the explanation of finding the degree of freedom of a rigid body when it’s fixed at a point.
