## Theorems And Formulas From the Class 11 Physics Chapter 9 Mechanical Properties Of Solids

 Sl No Term Description 1 Elasticity The ability of a body to regain to its original state, shape and size when deforming force gets withdrawn. 2 Stress Stress=F/A here, F is applied force and A is the area over which it acts. 3 Strain It is ration in the change in size or shape to the original size or shape. 4 Hooke’s Law Hooke’s law is the fundamental law of elasticity and is stated as ‘for small deformation stress is proportional to strain’. 5 Elastic Modulus Stress is proportional to Strain Stress/Strain=Constant This constant is termed as modulus of elasticity of a given material. 6 Poisson’s ratio The ratio of lateral strain to the longitudinal strain is called Poisson’s ratio which is a constant for the material of the body. 7 Strain Energy Energy stored per unit volume in strained wire is E=½(Stress)x(strain)
