What Will Be The Degree Of Freedom Of A Rigid Body If one point of the body fixe?

The degree of freedom of a rigid body when one point of the body is fixed is zero. This means that the rigid body has no motion at all as it is completely pinned down by the fixed point. Any movement of the rigid body would cause it to become non-rigid.

The degrees of freedom of a rigid body are expressed in terms of six independent parameters which are:

• Translation in three orthogonal directions
• Rotation around three orthogonal axes

When one point of the rigid body is fixed the body cannot move in any of these directions resulting in a degree of freedom of zero.
