What is Youngs modulus of rigid body and explain?

Answer: Young’s Modulus = Stress/Strain, Since a perfectly rigid body won’t yield any strain, irrespective of amount of stress, it’s Young’s modulus is infinite.

What is Young’s modulus for a perfectly plastic body?

zero
Young’s modulus for a perfectly plastic body is zero.

What is the Young’s modulus and bulk modulus of a perfectly rigid body?

Young’s modulus is infinite and bulk modulus is zero.

What is the value of Young’s modulus for a perfectly rigid body 1?

Young’s modulus is zero and bulk modulus is also zero.

What is Young’s modulus answer?

Young’s modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. Sometimes referred to as the modulus of elasticity, Young’s modulus is equal to the longitudinal stress divided by the strain.

Is Young’s modulus for a perfectly plastic body is zero?

We know a perfectly plastic body cannot regain its original shape when pressure is applied on it. That means the young’s modulus of a perfectly plastic body is zero.

What is a perfectly plastic body?

Perfectly elastic body: A body which does not regain its original configuration at all on the removal of the deforming force, however small the deforming force may be, is called a perfectly plastic body. The body which does not have the property of opposing the deforming force, is known as a plastic body.

Which one of the following statement is wrong Young’s modulus for a perfectly rigid body is zero?

From the above explanation we can conclude that statement A is incorrect, hence the answer is option A, because the young’s modulus for perfectly rigid bodies is infinity because the denominator of young’s modulus becomes zero, while for perfectly non-rigid bodies it is zero.

What is perfectly rigid?

In physics, a rigid body (also known as a rigid object) is a solid body in which deformation is zero or so small it can be neglected. In the study of special relativity, a perfectly rigid body does not exist; and objects can only be assumed to be rigid if they are not moving near the speed of light.

What is the Young’s modulus for a perfect rigid body Class 11?

infinite
Since a perfectly rigid body will not deform or won’t yield any strain(that is,strain=0), irrespective of amount of stress, it’s Young’s modulus is infinite.

How does Young’s modulus change with temperature?

With rise in temperature, the length of the material increases which decreases its stiffness. Thus, we can say that with rise in the temperature, the Young’s modulus decreases.

What is the Young’s modulus of perfectly rigid body material?

Thus the Young’s modulus of perfectly rigid body material is infinite. Was this answer helpful?

What is youngyoung’s modulus?

Young’s modulus is a mathematical constant. It was named after Thomas Young, an 18th-century English physician and scientist. It defines the elastic characteristics of a solid that is subjected to tension or compression only in one direction.

What is the modulus of rigidity of aluminum?

The modulus of rigidity depends on the material. For example, the modulus of rigidity for cast steel is approximately 11 x 106 psi (or 78 GPa), the modulus of rigidity of concrete is 3 x 106 psi (or 21 GPa), and the modulus of rigidity of aluminum is approximately 4 x 106 psi (or 28 GPa).

What is the modulus of shear modulus?

Similar to the modulus of elasticity, shear modulus is another form of the generalized Hook’s Law. The modulus of rigidity depends on the material.
