Question: Which Force Is Responsible For The Elastic Nature Of A Body?

Can a rigid body be elastic?

A rigid body can be elastic..

Is gravity an elastic force?

The measure of the amount of matter in an object. The gravitational force exerted on a person or object at the surface of a planet. Occurs when the only force acting on an object is gravity. … An elastic force that stretches or pulls matter.

Which material has maximum elastic limit?

rubberIt is the highest limit of the material before the plastic deformation of the material can occur. Once the stress or force is removed from the material, the material comes back to its original shape. Elastomers like rubber have the highest elastic limit. The behavior can be explained by Hooke’s law.

How do you test for elasticity?

The elasticity test You measure the elasticity of your hair by stretching a curl and observing how quickly the curl returns. If the curl does not bounce back – or not quickly – it is a sign of too little moisture. A more specific test is as follows: Take a loose hair and wash it with dish soap.

Why steel is most elastic?

So, it can be said that for a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.

What is elastic force example?

An example of elastic force is bungee jumping. The elastic cord creates resistance and imposes a force when the cord is stretched far enough. That elasticity creates the bouncing motion a bungee jumper feels after the initial jump, while the cord works to return to its normal size.

What are two types of elastic forces?

Matter is elastic if it returns to its original shape after it is squeezed or stretched; There are two types of elastic forces- compression and tension.

What are 4 factors that affect elasticity?

The four factors that affect price elasticity of demand are (1) availability of substitutes, (2) if the good is a luxury or a necessity, (3) the proportion of income spent on the good, and (4) how much time has elapsed since the time the price changed.

What is the cause for elasticity?

Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. … For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied.

What is an elastic body?

[i′las·tik ′bäd·ē] (mechanics) A solid body for which the additional deformation produced by an increment of stress completely disappears when the increment is removed. Also known as elastic solid.

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.

What happens to rocks when their elastic limit is reached?

Rocks can bend and stretch up to a point. But once a rock’s elastic limit is passed, the rock breaks. When rocks break in this way, they move along surfaces, or faults. A fault is the surface along which rocks move when they pass their elastic limit and break.

How do you find elastic limit?

In equation form, Hooke’s law is given by F=kΔL F = k Δ L , where ΔL is the change in length. Elasticity is a measure of how difficult it is to stretch an object. In other words it is a measure of how small k is. Very elastic materials like rubber have small k and thus will stretch a lot with only a small force.

What are the 4 types of elasticity?

Four types of elasticity are demand elasticity, income elasticity, cross elasticity, and price elasticity.

What is elastic body and plastic body?

elastic body and plastic body a body. that regains its original shape and size on the removal of deforming. force within the elastic limit is called an elastic body elasticity. … that does not regain its original shape. and size after the removal of deforming force is called a plastic body.

Which force is responsible for elastic Behaviour?

Restoring forceRestoring force is responsible for the elastic behavior of substance.

What are elastic forces?

Elasticity is the ability of a material to return to its original shape after being stretched or compressed. When an elastic material is stretched or compressed, it exerts elastic force. This force increases the more the material is stretched or compressed.

Which substance is more elastic?

rubberElasticity is the ability of a material to regain its own original shape after being stretched according to which, rubber is the most elastic substance. But when we define elasticity in physics it is the ratio of stress to strain. It means that the shape which has more resistance to change is more elastic.
