Question

explain the terms elasticity,plasticity and stress terms in physics clearly and detailedly

Answer 1

The objects which after deformation gets in their original shape are called as Elastic objects and the property is known as Elasticity.

Those which after deformation do not able to gain their original shape is known as Plastic objects and the property is known as plasticity..

Stress is defined as the restoring force acting per unit area.
For eg if you push a rubber block against a wall, the restoring force will act on the body against the Applied force.
Also stress characterise the strength of the force causing the deformation.

Stress are of following types

Tensile stress which is defined as tensile force per unit area

Bulk stress which is defined as the fluid force per unit area

Shear stress which is defined as force applied tangentially to a surface.

Hope you get your answer.

Answer 2

Hi,

Here is your answer,

What is Elasticity?

The property to restore the natural shape or to oppose the deformation is called Elasticity !

Stress is defined as force acting per unit cross section area is called stress.

The ratio of chain produced in the dimension of a body length, volume, angular Reformation.

The original dimension is called strain.

That is Chain in dimension/original/ original dimension !

It has no units.

(Extra information regarding Strain)

Stress is of 3 types!

Longitudinal and Shearing Stress


The resultant so that the centre of mass remains at rest. Due to the forces is zero so that the centre of mass remains at rest. Due to the forces , the body gets deformed and internal forces appear. Consider any cross- sectional area (DELATA)S of the body on the two sides of (Delta)S exert forces F ( Bar) - F( Bar) on each other! These internal forces F(bar) -F(bar) (bar it is a symbol) appear because of the deformation!

The longitudinal stress can be of two types. The two parts of the body on the two sides of (Delta)S may pull each other. The longitudinal stress is then called the tensile stress.

Longitudinal stress is also called compressive stress.

Volume Stress:- This is an another type of stress occurs when a body is acted upon by forces acting everywhere on the surface and the magnitude of the force on any small surface area is proportional to the area.

The force acting per unit area is then called volume stress.







What is plasticity? Plasticity is a property of substances to alter it's shape in simple words ! Hope it helps you!
