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1	Elasticity	The ability of a body to regain to its original state, shape and size when deforming force gets withdrawn.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)
