What causes atomic elasticity?

The elasticity of steel and other metals arises from short-range interatomic forces that, when the material is unstressed, maintain the atoms in regular patterns. Under stress the atomic bonding can be broken at quite small deformations.

What is the cause of elasticity of an object?

ELASTICITY is the ability of an object to restore it’s original shape and size when it is deformed by some internal forces generated due to external forces. By applying a deforming force which leads to compression or expansion of an elastic material causes elasticity.

What do the atoms do in elastic deformation?

In other words, elastic deformation is a change in shape of a material at low stress that is recoverable after the stress is removed. This type of deformation involves stretching of the bonds, but the atoms do not slip past each other.

What are the factors which affect the elasticity of a material?

(i) Effect of temperature: On heating, mostly the elasticity of materials decreases. (ii) Effect of impurities: Depending upon the nature of impurity, the elasticity of materials may increase or decrease. (iii) Annealing: Annealing decreases the elasticity of materials.

What is the cause of elasticity Class 11?

When an external force is applied to a rigid body there is a change in its length, volume (or) shape. When external forces are removed the body tends to regain its original shape and size.

Which is elastic material answer?

Elastomers are elastic materials that regain their original shape if they are distorted. Some common elastomers are rubber, a naturally occurring polymer of isoprene, and neoprene, a synthetic polymer of 2-chloro-1,3-butadiene.

What force is caused by elasticity?

Elasticity is the ability of a material to return to its original shape after being stretched or compressed. When an elastic material is stretched or compressed, it exerts elastic force. This force increases the more the material is stretched or compressed.

What causes elastic deformation?

Elastic deformation can be caused by applying shear forces or tension / compression stress. In contrast, plastic deformation occurs when these stresses are sufficient to permanently deform the metal. In plastic deformation, breaking of bonds is caused by the dislocation of atoms.

How does elasticity work on an atomic level?

In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). This is known as perfect elasticity, in which a given object will return to its original shape no matter how strongly it is deformed.

Which factor do not affect the elasticity of a material?

Temperature: As the temperature increases, intermolecular forces decreases, resulting in a decrease in the elasticity. But elasticity of invar steel is not dependent on the temperature. Impurities: Depending on the nature of the impurities, the elasticity of a material can either increase or decrease.

What is elastic hysteresis in physics class 11?

Elastic Hysteresis is the difference between the strain energy required to generate a given stress in a material, and the material’s elastic energy at that stress. This energy is dissipated as internal friction (heat) in a material during one cycle of testing (loading and unloading).

What are the 4 types of elasticity in physics?

There are three types of modulus of elasticity, Young’s modulus, Shear modulus, and Bulk modulus….Elasticity:

Deforming Force	Elasticity
Hooke’s Law	Elastic Modulus
Types of Modulus of Elasticity	Poisson’s Ratio
Stress and Strain Curve	Thermal Stress
