Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.
How do you solve elasticity in physics?
ΔL= 1YFA 1 Y F A L0, whereΔL is the change in length,F the applied force,Y is a factor, called the elastic modulus or Young’s modulus, that depends on the substance,A is the cross-sectional area, andL0 is the original length.
What is elasticity in physics PDF?
• elasticity is the ability of a body to resist a distorting. influence or deforming force and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate forces are applied on them.
What is elasticity and example in physics?
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.
What is the formula for elastic force?
Hooke’s law gives us the force we need to find elastic potential energy. Looking at a graph of force versus displacement, we can find that the formula for elastic potential energy is PE = 1/2(kx^2).
What are the 3 types of elasticity in physics?
Elastic Moduli can be of three types, Young’s modulus, Shear modulus, and Bulk modulus.
What are the types of elasticity?
Four types of elasticity are demand elasticity, income elasticity, cross elasticity, and price elasticity.
What is cause of elasticity?
For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Hooke’s law states that the force required to deform elastic objects should be directly proportional to the distance of deformation, regardless of how large that distance becomes.
What is the most elastic material?
The correct answer is Steel. Steel is the most elastic material. If the object is elastic, the body regains its original shape when the pressure is removed. Steel having the steepest linear stress-strain curve among all.
What is the SI unit of Young’s modulus?
What is the SI unit of Young’s modulus? Pascal is the SI unit of Young’s modulus.
Why steel is more elastic than rubber?
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 called elasticity?
elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically. Hooke’s law.
What is elastic example?
Elastic Demand Note that a change in price results in a large change in quantity demanded. 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.
Which material is an example of elasticity?
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 type of force is elastic?
Elasticity and Elastic Force As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force. The farther the material is stretched or compressed, the greater the elastic force becomes.
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 is elastic strain energy?
Strain energy is a type of potential energy that is stored in a structural member as a result of elastic deformation. The external work done on such a member when it is deformed from its unstressed state is transformed into (and considered equal to the strain energy stored in it.
What is elastic limit of a body?
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 is stress and strain in elasticity?
Stress and strain have a straight proportional relationship up to an elastic limit. The relationship between stress and strain is explained by Hooke’s law. Hooke’s law states that the strain in a solid is proportional to the applied stress, which must be within the solid’s elastic limit.
What is an elastic material?
Elastic materials are types of materials that get back to their original shape after getting stretched by an external force. For example, rubber is an elastic material because it is stretched when force is applied to it but returns to its original shape once the forces are removed.
What are elastic applications?
Elastic applications can allocate and deallocate resources (such as VMs) on demand for specific application components.
What is maximum load in elasticity?
Elastic limit: Elastic limit is the maximum load (force) which a body can experience and still retain its original size/shape once the load/force has been removed. It can also be defined as “the point on a stress/strain or load/extension graph beyond which Hooke’s law is no longer obeyed. 2.
Is metal elastic or inelastic?
Rubber band: elastic. Metal wires: inelastic, ductile.
What are the 4 types of demand?
There are four types of demand namely Competitive Demand, Joint or Complementary Demand, Composite Demand and Derived Demand.
Is gas elastic or inelastic?
Gasoline is a relatively inelastic product, meaning changes in prices have little influence on demand.
