Modulus Of Elasticity


Let us learn about "Modulus Of Elasticity"

Modulus of elasticity, also known as elastic modulus or Young’s Modulus, is a measure of how a material or structure will deform and strain when placed under stress. Materials deform differently when loads and stresses are applied, and the relationship between stress and strain typically varies. The ability of matter to resist or transmit stress is important, and this property is often used to determine if a particular material is suitable for a specific purpose.

Corresponding to the three types of strain, there are three moduli of elasticity.

(i) Young's modulus, corresponding to longitudinal strain,

(ii) Bulk modulus, corresponding to volume strain and

(iii) Rigidity modulus, corresponding to shearing strain.

E=a constant of proportionality known as modulus of elasticity or young's modulus. numerically, it is that value of tensile stress, which when applied to a uniform bar will increase its length to double the original length if the material of the bar could remain perfectly elastic throughout such an excessive strain.


In our next blog we shall learn about "ideal gas constant"


I hope the above explanation was useful. Keep reading and leave your comments.
