Q1. What is stress and strain

Ans.

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

Stress is the force applied to a material per unit area
Strain is the resulting deformation or change in shape of the material
Stress is measured in units of force per unit area (such as N/m^2 or Pa)
Strain is a dimensionless quantity representing the amount of deformation relative to the original size of the material

Q2. What is elastic properties

Ans.

Elastic properties refer to the ability of a material to deform under stress and return to its original shape when the stress is removed.

Elastic properties include Young's modulus, shear modulus, and Poisson's ratio.
Young's modulus measures the stiffness of a material in tension or compression.
Shear modulus measures the stiffness of a material in shear.
Poisson's ratio describes the ratio of lateral strain to axial stra...
