Question

Define Hooke's law of elasticity, proportionality, permanent set and breaking stress.

Answer 1

Hii dear,

◆ Hooke's law -
Within the elastic limit, stress on body is directly proportional to strain produced in it.
Stress = E × Strain
Where, E = Modulus of elasticity

◆ Proportionality limit-
It's the maximum stress applied on the body within which it follows Hooke's law.

◆ Permanent set-
When the wire is extended beyond permissible limits, permanent deformation sets in called as permanent set.

◆ Breaking stress-
Maximum stress the wire can bear beyond which it breaks is called breaking stress.

Hope that was useful...

Hey brainly user !

Here is your answer

$\color{blue}\huge\bold\star\underline\mathcal{Hooke's\:law\:of\:elasticity}\star$

Within the elastic limit, stress is directly proportional to strain

∴Stress ⋉ Strain

⇛Stress =E(strain)

Here E is called as modulus of elasticity

Personality limit :The limit Upto which the stress is directly proportional to the strain is called Proportionality limit

Permanent set :The permanent deformation that is produced in the wire when it is stretched beyond the elastic limit

Breaking stress : The stress for which the wire breaks is called breaking stress
