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.

What is instantaneous centre of rotation?
The instantaneous center of rotation is a point in a rigid body that has zero velocity at a specific moment in time. It is the point around which all parts of the rigid body have rotation at that moment. It helps to analyze the motion of the rigid body at that instant.
What is the moment of inertia about the instantaneous center in a rotating rigid body?
The moment of inertia about the instantaneous center in a rotating rigid body is a measure of how difficult it is to change the body's rotational motion around that point. It depends on the mass distribution and shape of the body.
What is Difference between elastic body and rigid body?
An elastic body can deform under stress but will return to its original shape when the stress is removed, while a rigid body does not deform at all. In other words, an elastic body can store and release energy in the form of deformation, while a rigid body cannot.
What happens to all the points in a rigid body when it rotates about a fixed axis?
When a rigid body rotates about a fixed axis, all the points in the body move in circular paths around that axis.
What are the difference between the particle and rigid body?
Particles are point-based objects with no dimensions or orientation, used to simulate small particles in a system. Rigid bodies are solid objects with dimensions and orientation that interact with other objects in a physics simulation. Rigid bodies have mass, volume, and inertia, while particles are massless and do not have volume or shape.
What is instantaneous centre of rotation?
The instantaneous center of rotation is a point in a rigid body that has zero velocity at a specific moment in time. It is the point around which all parts of the rigid body have rotation at that moment. It helps to analyze the motion of the rigid body at that instant.
Is there such a thing as truly rigid body?
In classical physics, a rigid body is an idealization where the distance between any two points on the body remains constant. However, in reality, all physical bodies have some degree of flexibility or deformation under certain conditions. Therefore, there is no truly rigid body in practice.
What is the moment of inertia about the instantaneous center in a rotating rigid body?
The moment of inertia about the instantaneous center in a rotating rigid body is a measure of how difficult it is to change the body's rotational motion around that point. It depends on the mass distribution and shape of the body.
Principle of transmissibility?
The principle of transmissibily states that the the conditions of equilibrium(uniform mothion) of a rigid body will remain unchanged if a force acting at a given point of the rigid body is tansmitted along its line of action to another point with the same magnitude and same direction.
Does a hamster have a rigid body?
It has a rigid skeleton but the body is flexible.
How does your body hold itself up?
that's basically the point of your bones. they're rigid so can be kept straight by your muscles. you naturally have a sense of balance so can keep your bones rigid
What is the Formula for center of mass?
Center of mass = [(mass of a point object)*(distance of that point from origin)]/(Total mass) For a rigid body we need to integrate this expression.
How does a rigid body differ from an elastic body?
A rigid body does not deform under stress, maintaining its shape, while an elastic body can deform under stress but will return to its original shape once the stress is removed. Rigid bodies are idealized as having infinite stiffness, while elastic bodies have finite stiffness allowing for deformation.
What is the use of shear force and bending moment diagrams?
To determine the internal shear forces and moments at any given point on a rigid body.
A rigid bar that pivots about a fixed point?
function calling stands for the function consists of semicolean but the called function is refers to the body of the function.
Difference between rigid body and particle?
The key difference between a particle and a rigid body is that a particle can undergo only translational motion whereas a rigid body can undergo both translational and rotational motion
How do you locate a center of mass?
Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero. Center of mass = [(mass of a point object)*(distance of that point from origin)]/(Total mass) For a rigid body we need to integrate this expression.
