The property of a body , by the virtue of which material bodies regain their original dimensions (size, shape or both) after removal of deforming forces is called elasticity .
 
Plasticity
 
Plasticity is the property of a body to undergo permanent deformation even after the removal of deforming forces .
 
Rigidity
 
Deformation α Deforming Force
Strain α Stress
Stress / Strain = Constant
 
Stress And Strain
 
1) Longitudinal Stress & Strain (along length)
 
Longitudinal Stress = Applied Force / Cross Section Area
Longitudinal Strain = ( l - l0 ) / l0 = ΔL / L
 
2) Volume Stress & Strain (with Volume)
 
Volume Stress = Applied Force / Volume
Volume Strain = ΔV / V
 
3) Shearing Stress & Strain (with shape)
 
Shearing Stress = Tangential Applied Force / Area
Shearing Strain = θ
 
Elasticity Modulus (Hooke's Law)
 
(Young's Modulus and Hooke's Law for JEE)
Deformation α Deforming Force
Strain α Stress
Stress / Strain = M; where M is a constant , called as Modulus of Elasticity .
 
Young's Modulus
 
(for longitudinal strain and stress)
Y = Longitudinal Stress / Longitudinal Strain
 
Bulk Modulus
 
(for Volume Strain and Strain)
K = Volume Stress / Volume Strain
Compressibility = 1 / Bulk Modulus
Modulus of Rigidity
(for Shearing Strain and Stress)
η = Shearing Stress / Shearing Strain
 
Poisson's Ratio
 
ς = lateral strain / longitudinal strain
Determination of Elasticity Modulus
 
Elastic Energy
 
Strain Energy = 1/2 load x extension
Strain Energy per unit volume = 1/2 x (Strain)2
Strain Energy is defined as an elastic potential energy gained by a wire during elongation by stretching force
