Which is an example of elastic behavior?

When we stretch a slingshot, it has been deformed due to the applied force, and again its original shape has been regained, when we stop applying the force, which is called elasticity, that means when stress is being applied the body resists any permanent change.

What is elastic behaviour 11th class?

Elasticity is the ability of a body to resist any permanent changes to it when stress is applied. The body regains its original shape and size when stress application ceases.

What is elastic behavior and plastic behavior?

When energy goes into changing the shape of some material and it stays changed, that is said to be plastic deformation. When the material goes back to its original form, that’s elastic deformation. Mechanical energy is lost whenever an object undergoes plastic deformation.

What is an example of elastic in physics?

A rubber band stretches and returns to its original shape, displaying elasticity.

What is elasticity and example?

Elasticity is the ability of an object or material to resume its normal shape after being stretched or compressed. Example: A rubber regains its shape after long stretch because of its elastic property.

Why any material shows elastic behaviour?

Solids are made up of atoms based on their atomic elasticity (or molecules). They are surrounded by other atoms of the same kind, which are maintained in equilibrium by interatomic forces. When an external force is applied, these particles are displaced, causing the solid to deform.

What is state Hooke’s Law?

Mathematically, Hooke’s law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. The value of k depends not only on the kind of elastic material under consideration but also on its dimensions and shape.

What are the applications of elastic behaviour of Class 11?

  • Metallic part of machinery is never subjected to a stress beyond the elastic limit of the material.
  • Metallic rope used in cranes to lift heavy weight is decided on the elastic limit of the material.
  • In designing beam to support load (in construction of roofs and bridges).

Which is elastic material example?

Elastomers are elastic materials that regain their original shape if they are distorted. Some common elastomers are rubber, a naturally occurring polymer of isoprene, and neoprene, a synthetic polymer of 2-chloro-1,3-butadiene.

What is the difference between elastic and plastic Behaviour of materials?

The main difference between the elastic and the plastic material is the behavior of their structures. Elastic materials will break when they reach their elastic limit whereas the plastic material will not break.

What’s the difference between elasticity and plasticity?

1. Elasticity is the property of a solid material that allows it to restore its shape after an external load is removed. Plasticity is the property of a solid substance that allows it to keep its deformed shape even when the external load is removed.

What is the difference between elastic and plastic body?

1) Elasticity is the property of solid material that it gains its original shape and size after the removal of applied force. 1)Plasticity is the property of solid material that it does not gain its original shape and size after the removal of applied force.

What is elastic and inelastic collision in physics?

A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.

What are 5 examples of elastic energy?

  • The coil spring of a wind-up clock.
  • An archer’s stretched bow.
  • A bent diving board, just before a divers jump.
  • The twisted rubber band which powers a toy airplane.
  • A bouncy ball, compressed at the moment it bounces off a brick wall.

How do you explain elasticity?

Elasticity is a measure of a variable’s sensitivity to a change in another variable, most commonly this sensitivity is the change in quantity demanded relative to changes in other factors, such as price.

What are the 3 types of elasticity?

Elasticity is a general measure of the responsiveness of an economic variable in response to a change in another economic variable. The three major forms of elasticity are price elasticity of demand, cross-price elasticity of demand, and income elasticity of demand.

Which is the best example of elastic demand?

An example of products with an elastic demand is consumer durables. These are items that are purchased infrequently, like a washing machine or an automobile, and can be postponed if price rises. For example, automobile rebates have been very successful in increasing automobile sales by reducing price.

What makes a material elastic?

A material becomes deformed when a stress is applied to it. Its elasticity is the material’s ability to return to its original form once the stress is removed.

Is metal elastic or inelastic?

Rubber band: elastic. Metal wires: inelastic, ductile.

What is elastic properties of materials?

Elasticity is defined as a physical property of materials which return to their original shape after the stress that had caused the deformation is no longer applied.

What is Hooke’s Law and Young’s modulus?

Hooke’s law is a fondamental rule of thumb applied on skin that describes a direct proportionality link between the force applied on an object and the induced strain. Young’s Modulus is a constant coefficient stiffness*, named k, which describes how stiff is the skin or how likely it is to deform.

Where is Hooke’s law used?

It is used in breathing (lungs), skin, spring beds, diving boards and cars suspension systems. It is used as a fundamental principle behind the manometer, spring scale and balance wheel of the clock. It is also used as the foundation for seismology, acoustics and molecular mechanics.

What is Hooke’s Law example?

A balloon is elastic in nature. When the air molecules are blown in it, it expands. Similarly, when it is evacuated, it shrinks in size. The expansion and compression of the balloon depend on the force with which the air is pressed into it; therefore, it works on the basis of Hooke’s law.

What is the use of elastic force?

When an elastic material is stretched or compressed, it exerts elastic force. This force increases the more the material is stretched or compressed. Elastic force has many uses, from hair scrunchies to bed springs.

What are the uses of elasticity?

Elasticity is an important economic measure, particularly for the sellers of goods or services, because it indicates how much of a good or service buyers consume when the price changes. When a product is elastic, a change in price quickly results in a change in the quantity demanded.
