There is no perfectly elastic body but quartz fibre and Phosphor bronze are examples of near perfect elastic bodies. If a body does not regain its original configuration at all after the deforming force is removed, it is called perfectly plastic body. Examples of near perfect plastic bodies are wax, putty etc.
What is elastic body give two examples?
Quartz fibre and Phosphor bronze are the examples of perfectly elastic body.
What are elastic bodies?
A deformable solid body is called elastic if its deformation disappears with the removal of the forces that caused this deformation. When an elastic body is restored to its initial form, it returns completely the work that was expended for the deformation.
Which is the most elastic body?
Steel is more elastic than rubber. This is explained with the help of Young’s modulus.
Which of the following is an example of elastic material?
The materials that can be stretched and when released attains their original shape and size are known as elastic materials. Rubber band is an example of elastic material.
What makes something elastic?
A product is considered to be elastic if the quantity demand of the product changes more than proportionally when its price increases or decreases . ... Price decreases also do not affect the quantity demanded; most of those who need insulin aren’t holding out for a lower price and are already making purchases.
Is Clay elastic or inelastic?
Examples: Rubber bands and elastic and other stretchy materials display elasticity. Modeling clay, on the other hand, is relatively inelastic and retains a new shape even after the force that caused it to change is no longer being exerted.
Which ball is more elastic?
When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape.
Why is rubber not elastic?
The ratio of stress applied on a body to the strain produced in it is defined as the Young’s modulus of that material. ... Rubber gets stretched because there is strain produced in it when stress is applied. The larger strain means the material is less elastic .
Which is more elastic in nature?
Steel is more elastic than rubber. This is explained with the help of Young’s modulus.
What are the examples of elastic force?
- Bungee Jumping.
- Elastic Waistband.
- Rubber Bands.
- Resistance Band.
- Spring Toys.
- Spring Mattress.
- Trampoline.
- Bow.
What are the elastic properties of materials?
Elasticity: Property by virtue of which materials regain their original shape and size after the removal of deforming forces . The elastic limit of a substance is defined as the maximum stress that can be applied to the substance before it becomes permanently deformed and does not return to its initial length.
Is 0.5 elastic or inelastic?
Demand for a good is said to be elastic when the elasticity is greater than one. A good with an elasticity of -2 has elastic demand because quantity falls twice as much as the price increase; an elasticity of -0.5 has inelastic demand because the quantity response is half the price increase.
How do you tell if a graph is elastic or inelastic?
If a demand curve is perfectly vertical (up and down) then we say it is perfectly inelastic . If the curve is not steep, but instead is shallow, then the good is said to be “elastic” or “highly elastic.” This means that a small change in the price of the good will have a large change in the quantity demanded.
Are cars elastic or inelastic?
For example, the demand for automobiles would, in the short term, be somewhat elastic , as the purchase of a new vehicle can often be delayed. The demand for a specific model automobile would likely be highly elastic, because there are so many substitutes.
