What are elastic solids?
An elastic solid is a deformable continuum that possesses the property of recovering its original configuration when forces causing deformation are removed. An elastic solid that undergoes only an infinitesimal deformation and for which the governing material law is linear is called a linear elastic solid.
What is elastic example?
Most commonly, elasticity refers to an economic gauge that measures the change in the quantity demanded for a good or service in relation to price movements of that good or service. For example, when demand is elastic, its price has a huge impact on its demand. Housing is an example of a good with elastic demand.
What are elastic materials?
What are elastic materials? Elasticity is the tendency of solid materials to return to their original shape after forces are applied on them. When the forces are removed, the object will return to its initial shape and size if the material is elastic.
Are all solids elastic?
To a greater or lesser extent, most solid materials exhibit elastic behaviour, but there is a limit to the magnitude of the force and the accompanying deformation within which elastic recovery is possible for any given material.
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.
Is wire elastic or inelastic?
Metal wires: inelastic, ductile.
Is glass elastic or plastic?
Glass can typically be classified as an elastic material. In fact, glass is known to be more elastic than rubber because for a given applied force per unit area, the strain produced in glass is known to be much smaller than that produced in rubber.
Is spring elastic or inelastic?
A spring is an example of an elastic object – when stretched, it exerts a restoring force which tends to bring it back to its original length. This restoring force is generally proportional to the amount of stretch, as described by Hooke’s Law.
Which is the most elastic material?
Which is more elastic Mcq?
Air is more elastic than water.
Which is least elastic material?
Is rubber more elastic than steel?
The strain produced in rubber is much larger compared to that in steel. This means that steel has a larger value of Young’s modulus of elasticity and hence, steel has more elasticity than rubber.
What is elastic limit?
Elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape. Stresses beyond the elastic limit cause a material to yield or flow.
Why is iron more elastic than rubber?
Since, the iron rod regains its original configuration more efficiently than rubber, it is iron which is more elastic than rubber. In the above case of rubber band and iron rod, rubber band is more plastic because it is not able to regain its original configuration after the deforming forces are removed.
Why glass is more elastic than rubber?
(a) Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than the strain produced in rubber.
Why is rubber so elastic?
Natural rubber is made of long chains of molecules called polymers. Because these polymers are so long (they can be thousands of molecules long) they get tangled up in themselves. The result is a property called elasticity, the polymers are elastic. This is why rubber bands are sometimes called elastic bands.
Why is glass elastic?
Glass is a perfectly elastic material: it does not exhibit permanent deformation, until breakage. This modulus expresses the tensile force that would theoretically have to be applied to a glass sample to stretch it by an amount equal to its original length.
Which is a type of elasticity?
We mentioned previously that elasticity measurements are divided into three main ranges: elastic, inelastic, and unitary, corresponding to different parts of a linear demand curve. Demand is described as elastic when the computed elasticity is greater than 1, indicating a high responsiveness to changes in price.
Is Samsung price elastic?
Because the Price elasticity of demand for Samsung is high, increased prices has result in less demand for its smartphones. They are however, offering these phones at prices that are much cheaper and affordable.
