Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.

SteveThe proportional limit is the point at which stress and strain are directly proportional, before the material starts to deform plastically. In contrast, the elastic limit is the point at which the material can no longer return to its original shape after stress is removed, indicating permanent deformation.

What is Difference between elastic limit and proportional limit?
Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.
What is elastic limit and hooke's law?
The elastic limit is the maximum stress that a material can withstand without permanent deformation. Hooke's law states that the force applied to deform a solid object is directly proportional to the object's deformation, as long as the object remains within its elastic limit.
What is proportional limit?
The proportional limit is the maximum stress at which stress and strain remain proportional within a material. Beyond this point, the material begins to deform plastically and no longer exhibits linear elastic behavior. It is an important property in materials testing and design.
What is the difference the proportional limit and the yield point of a spring that has been over stretched?
The proportional limit is the maximum stress at which stress and strain are directly proportional. The yield point is the stress at which the material begins to deform plastically. If a spring has been overstretched beyond its yield point, it won't return to its original shape when the load is removed.
What is Proportional limit of a spring?
The proportional limit of a spring is the point at which the relationship between the force applied to it and the extension of the spring becomes non-linear. Beyond the proportional limit, the spring will no longer obey Hooke's Law, which states that the extension of a spring is directly proportional to the force applied to it.
