Question
State Hooke’s law. Define the elastic limit and modulus of elasticity.
Solution
Hooke’s law: Provided the elastic limit is not exceeded, the deformation of a material is proportional to the force applied to it.
`=> "stress"/"strain" = "k"`
k is known as modulus of elasticity.
Elastic limit: The maximum stress within which the body regains its original size and shape after removing of deforming force is called elastic limit.
Modulus of Elasticity: The modulus of elasticity or coefficient of elasticity of the body is defined as the ratio of stress to the corresponding strain within the elastic limit.
