no body is truely rigid body because we observe rigid body at microscopic level
The skeletal system provides rigid support for the body, through bones that form a framework to support and protect the internal organs. The bones also work with muscles to facilitate movement and provide structure to the body.
There are two system that do this. Your skeleton (bones) and your skin (integument).
The rigid structures that make up the skeleton are bones. The human skeleton is composed of 206 bones that provide support, protection, and leverage for movement. These bones are connected by joints, ligaments, and tendons to form a complete framework for the body.
The strongest tissue in the body is typically considered to be bone tissue. Bones are incredibly strong and rigid due to their mineral content, primarily calcium, which gives them their strength and hardness.
Yes, cartilage is a flexible connective tissue that provides support and cushioning to joints in the body. It is less rigid than bone but still has a firm and elastic structure.
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.
It has a rigid skeleton but the body is flexible.
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.
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 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.
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.
In statics a particle and a rigid body are viewed as pretty much the same thing, and can be analysed with the same methods. Assuming that a particle is in equilibrium i.e. the sum of the forces and the moments are all zero, and that a rigid body is made up of particles, we know that if each particle of this body is in equilibrium (internal forces cancel each other out) then we can conclude that the body must therefore also be in equilibrium. The difference between these a particle and a body is we will usually find a particle in space without these so-called constraints, while a rigid body- a beam comes immediately to mind, is usually constrained in some or other manner, by either a pin or roller or any other way.
False. Flaccid is the opposite of rigid. For example, in the medical field, there's flaccid paralysis and rigid paralysis. Flaccid paralysis is when a body part is unable to be moved, but there is no muscle tone. The body part is "floppy." Rigid paralysis is when the body part is unable to be moved, but there is a lot of muscle tone. The body part is "stiff."
