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.

Why does an elastic band stretch if there is weight on it?
The force exerted by the weight exceeds the force of the elasticity that normally keeps the elastic band in a contracted state. As the band stretches, the resistance increases to the point where it is equal to the force exerted by the weight.
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.
When an extension spring stores the most elastic energy when it is in which position?
An extension spring stores the most elastic energy when it is in its stretched position right before reaching its maximum extension. At this point, the spring is under the highest tension, which results in the maximum potential energy being stored in the form of elastic deformation.
What are examples of elastic materials?
All materials are elastic to a point. An elastic material is one that returns to its original size and shape when the load that is causing it to bend or stretch, is removed. At some point all materials will exceed their "elastic limit". Mild steel used for building structures is quite elastic if not over loaded. Rubber such as a rubber band is extremely elastic but it also has an elastic limit, and an ultimate strength. Glass is not very elastic and is considered brittle.
How do you attach elastic to ballet point shoes?
You have to sew it on.

How do you find elastic center?
elastic center is that point of a beam in the plane of the section lying midway between the flexural center & the center of the twist of th
What happens when the stress and strain of elastic deformation along tectonic plates reaches the breaking point?
When the stress and strain along tectonic plates reach the breaking point, it can result in an earthquake. This is when the stored elastic energy is released as seismic waves, causing the rocks on either side of the fault to move, releasing the built-up stress.
Why does an elastic band stretch if there is weight on it?
The force exerted by the weight exceeds the force of the elasticity that normally keeps the elastic band in a contracted state. As the band stretches, the resistance increases to the point where it is equal to the force exerted by the weight.
How will elastic limit be represented on a graph?
On a graph depicting stress versus strain, the elastic limit is represented as the point at which the curve begins to deviate from a straight line, indicating that the material will no longer return to its original shape after the load is removed. This point is typically marked at the end of the linear elastic region of the graph, where Hooke's Law is applicable. Beyond the elastic limit, the material enters the plastic deformation region, where permanent deformation occurs.
How do you distinguish yield point and elastic limit?
On a stress strain curve the elastic limit is the point where the straight portion curve first starts to curve. When load is removed strain will return to zero. The yield point is a point on the curve just beyond the elastic limit. When load is removed strain will not return to zero. It will return approximately as a straight line parallel to the original, and have an offset strain value. The yield point offset is arbitrary but usually defined as 0.2% (.002 permanent strain) as most common strain devices can measure that amount.
Can be stretched and then return to its own shape?
