What Is Elasticity?
Elasticity: Elasticity is an inherent property by virtue of which a body undergoing a change in length, volume, or shape due to the application of external forces, tends to regain its original length, volume, or shape as soon as the external forces are withdrawn. Bodies that can regain their original conditions completely on withdrawal of…

What Are Strain And Stress?
Strain: When a force or a system of forces acting upon a body produces a relative displacement between its parts and the change in length, volume, or shape may take place, then the body is said to be under the strain. The strain of a body is measured in the form of dimension per unit…

What Is Elastic Limit
Elastic Limit : There is a certain limit of the deforming forces up to which the behaviour of a body remains elastic, i.e, it regains its original shape or size after removal of deforming forces. This limit is called the elastic limit of the material of the body.

What Is Hooke’s Law?
Hooke’s Law: There is a certain limit of deforming forces up to which the behavior of a body remains elastic. This is called the elastic limit of the material of the body. Within this elastic limit, the stress is proportional to the strain. i.e, , i.e, . This is known as Hooke’s law. The constant…

What Are Young’s Modulus (Y) & Bulk Modulus (K)?
Young’s Modulus (Y): This modulus is defined as the ratio of longitudinal (tensile or compressive) stress to the corresponding strain within the elastic limit. Elastic Limit : There is a certain limit of the deforming forces up to which the behaviour of a body remains elastic, i.e, it regains its original shape or size after…

What Is Modulus Of Rigidity Or Shear Modulus?
Modulus of Rigidity or Shear Modulus: Modulus of rigidity is defined as the ratio of tangential stress to shear strain within the elastic limit. If a tangential force acts on a surface of the area , then the tangential stress is . This effect gives rise to the angle of shear . Then the Modulus…

What Is Poisson’s Ratio?
Poisson’s Ratio: When an object is elongated longitudinally in the direction of the tensile force, then there will be a lateral contraction. this means that the contraction is in a direction perpendicular to the direction of tensile force. The ratio of lateral strain to longitudinal strain within the elastic limit is called Poisson’s Ratio .…

Relation Among Young Modulus(Y), Bulk Modulus(K), Modulus of Rigidity, Poisson’s Ratio.
There are three types of elastic modulus. These are 1. Young’s Modulus(Y): This is defined as the ratio of longitudinal stress to the corresponding strain within the elastic limit. READ MORE 2. Bulk Modulus(K): This is defined as the ratio of the volume stress to the volume strain within the elastic limit. READ MORE 3.Modulus…

Show That The Shear Strain Of A Cube Is Equivalent To Linear Strains Of Half The Magnitude In Mutually Perpendicular Direction.
A shear is equivalent to a compression and an extension at right angle to each other: Let us consider a cube , having each side equal to with its lower face is fixed. Let us consider a tangential force is applied on the upper face , so that the cube is sheared to the new…

Calculate Work Done Per Unit Volume In A Strain. Or Calculate Strain Energy.
Strain Energy: When a body is strained, internal forces due to the elastic property of the body are set up and hence work must be done by the applied force against the internal forces. The work is stored up within the body as potential energy which is known as the energy of strain or strain…
