What is the difference between the elastic limit and yield strength in materials testing?
The elastic limit is the point at which a material can be deformed and return to its original shape when the force is removed. Yield strength is the point at which a material starts to deform permanently. In other words, the elastic limit is the maximum stress a material can withstand without permanent deformation, while the yield strength is the stress at which a material begins to deform permanently.
What is the difference between yield strength and tensile strength?
Yield strength is the point at which a material begins to deform permanently, while tensile strength is the maximum stress a material can withstand before breaking.
Critical stress at which material will start to flow?
The critical stress at which a material will start to flow is called the yield stress. It represents the point at which the material transitions from elastic deformation to plastic deformation, causing it to permanently deform under applied stress. Yield stress is an important mechanical property that determines the material's ability to withstand deformation.
When stress is applied unequally in different directions it is termed?
When stress is applied unequally in different directions, it is termed shear stress. Shear stress occurs when forces are applied parallel to a surface in opposite directions, causing the material to deform by sliding over itself.
What is the stiffness of a material?
Stiffness of a material is a measure of its resistance to deformation when subjected to an applied load. It indicates how much a material will deform under a given load. Materials with high stiffness will deform less under load, while materials with low stiffness will deform more.
What if material goes to plastic range?
It will permanently deform and not recover to its original state.
What criteria are applied to define a pure solid?
The material does not deform permanently / continuously when shear is applied (below the plastic limit).

What will happen if too much tension force is exerted on a spring?
Once you provide any material with a stress beyond its yield stress, it will deform plastically. In layman's terms, it will spring back partially once you let go, but you will permanently deform it.

When stress is applied unequally in different directions, it is termed shear stress. Shear stress occurs when forces are applied parallel to a surface in opposite directions, causing the material to deform by sliding over itself.
Is copper stronger then nickel?
Their mechanical material properties are very similar with copper coming out marginally higher in terms of yield strength. This is the amount of stress required to make the metal deform permanently.
The difference between elasticity and plasticity?
Elasticity is the tendency of material to temporarily deform when placed under stress and regains its original shape and size upon removal of stress.It spreads, it stretches; it alters to accommodate the strain. Plasticity is the tendency of a material deform permanently under the application of external load . Think clay, putty; it retains the shape or can be re-shaped into something entirely new. The point at which a material's elasticity turns into plasticity is considered that object's yield.
What is the stiffness of a material?
Stiffness of a material is a measure of its resistance to deformation when subjected to an applied load. It indicates how much a material will deform under a given load. Materials with high stiffness will deform less under load, while materials with low stiffness will deform more.
How force can make change in shape of object?
By applying force to an object, internal stresses are created within the object's material causing it to deform or change shape. If the force exceeds the object's strength, it may permanently alter its shape. This process is governed by factors like the type of material, magnitude of force, and the object's design.
What will happen to a material if the stress applied exceeds the ultimate strength?
hehe of course the material will be deform :)
