What is meant by limit of proportionality?
The limit of proportionality is the maximum stress at which stress is directly proportional to strain in a material. Beyond this point, the material will deform plastically and exhibit permanent deformation. It is an important property used to determine the elastic limit of a material.
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.
What happens when a spring stretched beyond limit?
When a spring is stretched beyond its limit, it reaches a point where it can no longer return to its original shape. This is known as the spring's elastic limit. If the spring is stretched beyond this limit, it will permanently deform or even break.
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 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 the limit of proportionality?
limit of proportionality is the point where the spring expands in a non linear way / limit of elasticity is the point where the spring doesn't come back to it original shape

What are the two key criteria of jus in bello?
The two key criteria of jus in bello are distinction and proportionality. Distinction requires that combatants differentiate between military targets and civilians, ensuring that attacks are directed only at legitimate military objectives. Proportionality demands that the anticipated collateral damage to civilian life and property must not be excessive in relation to the direct military advantage gained from an attack. These principles aim to limit the effects of armed conflict on people and property.
What happens when a spring stretched beyond limit?
When a spring is stretched beyond its limit, it reaches a point where it can no longer return to its original shape. This is known as the spring's elastic limit. If the spring is stretched beyond this limit, it will permanently deform or even break.
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 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.
How does spring constant vary with length?
The spring constant is directly proportional to the length of the spring. As the length of the spring increases, the spring constant also increases. This relationship holds true until a limit called the elastic limit, beyond which the spring may become permanently deformed.
What is limit of proportionality?
It is the point at which the stress-strain graph of a material deviates from being a straight line. It is the point at which a material stops obeying Hooke's Law
What is the difference between proportional limit and elastic 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 the difference between function and a relation?
Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.
What is difference between limit of proportionality and tensile strength?
The proportional limit is the stress value at which the stress is no longer linear with strain. After that, the material will begin to yield and become non-linear, or plastic, and then it will fail at a higher value called the tensile strength. For most metals, the proportional limit is well below the tensile strength; for example annealed stainless steel has a proportional limit near 30 ksi and tensile strength of 80 ksi; aluminum has a proportional limit of 35 ksi and tensile strength of 42 ksi.
