The relative position of the points on any object will not change at any application of force, then it is called rigid body. The relative position of the points on any object will not change at any application of force, then it is called rigid body.
It has a rigid skeleton but the body is flexible.
"The condition of equilibrium or motion of a rigid body is remain unchanged, if a force acting on the rigid body is replaced by another force of the same magnitude and same direction but, acting anywhere along the same line of action."
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.
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.
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
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.
A rigid body will have a natural frequency of vibration due to its mass and stiffness properties. When disturbed from its equilibrium position, the body will oscillate at this natural frequency. This frequency is determined by the body's physical characteristics and can be calculated using principles of dynamics.
Any body falling into a black hole will get completely destroyed. There is no such thing as an absolutely rigid body; a "rigid body" is an approximation that may help with some calculations, and such an approximation is valid (i.e., it's a good approximation) under certain circumstances, but a body will certainly not remain rigid under the extreme circumstances of a black hole.
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.
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 directionsRotation around three orthogonal axesWhen 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.
When a rigid body rotates about a fixed axis, all the points in the body move in circular paths around that axis.
