The coefficient of elasticity or modulus of elasticity is the measurement of the elastic property of a material. When a force is applied to a material, its extent of getting distorted varies from material to material. This constant gives an idea about the degree of distortion. Elasticity is represented using δ. Dimensional Formula The dimensional formula of any bodily amount is defined as the expression that represents how and which of the bottom portions are protected in that amount. It is denoted through enclosing the symbols for base portions with suitable strength in rectangular brackets []. An example is the Dimension Formula of Mass which is given as [M]. Application of Dimensional Analysis In real-life physics, dimensional analysis is a crucial part of the measurement. We use dimensional analysis for 3 main reasons: • To ensure that a dimensional equation is consistent. • Determining the relationship between physical quantities in physical phenomena • To switch from one system to another’s units. • Development of a fluid phenomena equation. • The number of variables necessary in an equation is reduced. Limitations of the dimensional equation • The principle of homogeneity of dimensions cannot be used for trigonometric and exponential expressions. The derivation is more complex and complicated. • The comparing terms or factors are less. • The correctness of the physical expressions depends only on dimensional equality. • It is majorly used in the case of dimensio...

Modulus of Elasticity is the basic feature that is used for the calculations of the response of the deformations when the value of stress is applied to it. The elastic constants are used to measure the deformation produced through a given stress system that is acting on a material. Dimensional formula The base of the dimensional formula of mobility has an appropriate and proportionate relation with proper dimensions. For instance, dimensional force is F = [MLT -2]. Elasticity and its behaviour When stress application stops, the body regains its unique shape and size. Various materials show diverse elastic behaviour. The study of a material’s flexible behaviour is extremely important. Almost every design plan necessitates knowledge of a material’s flexible conductivity. For example, while building a bridge, the amount of traffic that it can bear should be measured accurately in advance. Similarly, when building a crane to lift loads, it is important to remember that the rope’s extension does not exceed its elastic limit. The elastic behaviour of the material utilised must be considered first to solve the problem of bending under stress. Elastic behaviour of solids The atoms or molecules inside a solid body are shifted from their specified points or fixed points (equilibrium positions) when it is deformed, resulting in a shift in interatomic and molecular distances. The interatomic force strives to return the body to its initial position when this force is withdrawn. As a re...

There is nothing particularly magical about the shape of a coil spring that makes it behave like a spring. The 'springiness', or more correctly, the elasticity is a fundamental property of the wire that the spring is made from. A long straight metal wire also has the ability to ‘spring back’ following a stretching or twisting action. Winding the wire into a spring just allows us to exploit the properties of a long piece of wire in a small space. This is much more convenient for building mechanical devices. In mechanics, the force applied per unit area is what is important, this is called the stress (symbol σ \sigma σ sigma ). The extent of the stretching/compression produced as the material responds to stress is called the strain (symbol ϵ \epsilon ϵ \epsilon ). Strain is measured by the ratio of the difference in length Δ L \Delta L Δ L delta, L to original length L 0 L_0 L 0 ​ L, start subscript, 0, end subscript along the direction of the stress, i.e. ϵ = Δ L / L 0 \epsilon=\Delta L/L_0 ϵ = Δ L / L 0 ​ \epsilon, equals, delta, L, slash, L, start subscript, 0, end subscript . • Elastic deformation. When the stress is removed the material returns to the dimension it had before the load was applied. The deformation is reversible, non-permanent. • Plastic deformation. This occurs when a large stress is applied to a material. The stress is so large that when removed, the material does not spring back to its previous dimension. There is a permanent, irreversible deformation. ...

The law is named after 17th-century British physicist ut tensio, sic vis ("as the extension, so the force" or "the extension is proportional to the force"). Hooke states in the 1678 work that he was aware of the law since 1660. Hooke's equation holds (to some extent) in many other situations where an Hookean.

It is very useful when analyzing mechanical systems—and many physical objects are indeed rigid to a great extent. The extent to which an object can be perceived as rigid depends on the physical properties of the material from which it is made. For example, a ping-pong ball made of plastic is brittle, and a tennis ball made of rubber is elastic when acted upon by squashing forces. However, under other circumstances, both a ping-pong ball and a tennis ball may bounce well as ri...
