Question

What is Young's modulus?​

Answer 1

Answer:

please brainlist please please please

Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line. The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed. More deformation occurs in a flexible material compared to that of a stiff material. In other words:

Answer 2

Young's Modulus is the coefficient of elasticity when we observe the change in length of any solid body

Explanation:

• Hook's law gives the relation of stress and strain which states that stress is directly proportional to the strain the proportional constant is the coefficient of elasticity and one of them is the Young's modulus
• Young's Modulus is defined as the ration of stress and strain

                            $Young's modulus = \frac{stress}{strain}$  ( unit and dimension as that of stress)

Stress : it is the ratio of force and area or defined as force per unit area, unit is  N/m²

Strain : It the ratio of change in length when force is applied to the original length, it is a unit less and dimension less quantity
