When a material deforms, it does so in several stages. The first stage, called the elastic region of deformation, is linear in nature and not permanent. A stress can be applied, and once it's removed, the material will regain all of the deformation. The second stage, plastic deformation, is permanent. A material that has been stressed into the plastic region will regain the elastic deformation, but will permanently maintain the plastic.
The proportional strength is the point at which plastic deformation begins.

What are square numbers used for?
There are many physical phenomena which depend on squares. For example, the strength of gravitational or magnetic attraction between two bodies is inversely proportional to the square of the distance between them.
Are speed and distance directly proportional or inversely proportional?
Directly proportional. Greater speed - greater distance.
If two quantities are (proportional nonproportional) they have a constant ratio.?
The answer is proportional.
How do you know if something is proportional?
if somthing is proportional is will either be Multiplying or Diving
What makes two quantities proportional?
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
How is strength related to flexibility?
My trainer said that strength is directly proportional to flexibility.
Doubling the thickness of a rope will multiply its strength by how much?
Doubling the thickness of a rope will multiply its strength by approximately four times. This is because the strength of a rope is directly proportional to the cross-sectional area, which is proportional to the square of the thickness.
What is the gravitys strength on a black hole?
It depends on the mass of the black hole and your distance from it. The strength of gravity is directly proportional to the mass of the object and inversely proportional to the square of your distance from the center.
What is the strength of an electromagnet proportional to?
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.
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.
Is it true or false The strength of an electrical signal is directly proportional to to its frequency?
False. The strength of an electrical signal is not directly proportional to its frequency. The strength of an electrical signal is related to its amplitude, which is the height of the signal. Frequency, on the other hand, refers to the number of cycles of the signal that occur in a given unit of time.
How do the size of the current in the coil affect the strength of a electromagnet?
The strength of an electromagnet is directly proportional to the current flowing through the coil. Increasing the current in the coil increases the magnetic field strength produced by the electromagnet. This means that increasing the size of the current in the coil will make the electromagnet stronger.
The strength of an electrical signal is directly proportional to its frequency?
No, the strength of an electrical signal is not directly proportional to its frequency. In an electrical signal, the strength is typically measured by the amplitude or voltage of the signal, while the frequency refers to the number of cycles per second. The relationship between the strength (amplitude) and frequency of a signal depends on the specific circuit or system in which the signal is operating.
What does the strength of a gravitational force between two object depend on?
The strength of the gravitational force between two objects depends on their masses and the distance between them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them.
Is phosphor bronze has high compressive strength?
The compressive strength of Phosphor Bronze is directly proportional to the tensile strength, For example 1/2 hard phosphor bronze has a Tensile Strength of 60 to 75 ksi and a Yield Strength of 45 to 70. For typical engineering calculations, the compressive strength can be considered equal to the yield strength.
How do you apply inverse variation to problems?
If one value of a variable increases as another value of a different variable decreases in a mathematical equation, they are said to be inversely proportional or vary inversely. For example, the strength of the force of gravity decreases as the square of the interacting distance increases, so the strength of gravity is inversely proportional to the square of the distance, or strength ∝ 1/distance2.
How is flux related with the strength of the magnet?
directly proportional. the greater the flux per unit area, the stronger the field.
