What Is The Dimensional Formula Of Young’S Modulus?

How do you find the dimensional formula of Young’s modulus?

The dimensional formula for Young’s modulus is :A.





What is the dimensional formula of stress?

Therefore, stress is dimensionally represented as [M1 L-1 T-2].

What is the dimensional formula of refractive index?

Refractive Index is defined as the relative speed at which light moves through a material with respect to its speed in vacuum. As both the values belong to same quantity (speed), units gets nullified. So Refractive Index is dimensionless quantity. Dimensional Formula of Refractive Index= M0L0T0.

What is Young’s modulus of rigidity?

The modulus of rigidity is the elastic coefficient when a shear force is applied resulting in lateral deformation. It gives us a measure of how rigid a body is. The table given below briefs everything you need to know about rigidity modulus. Shear modulus is the ratio of shear stress to shear strain in a body.

What does a higher Young’s modulus mean?

The coefficient of proportionality is Young’s modulus. The higher the modulus, the more stress is needed to create the same amount of strain; an idealized rigid body would have an infinite Young’s modulus. Conversely, a very soft material such as a fluid, would deform without force, and would have zero Young’s Modulus.

What is the dimension of Young’s modulus?

Young’s modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. Sometimes referred to as the modulus of elasticity, Young’s modulus is equal to the longitudinal stress divided by the strain.
