Dimensional Formula of Strain

The dimensional formula of Strain is given by,

[M⁰ L⁰ T⁰]

Where,

• M = Mass
• L = Length
• T = Time

Derivation

Strain = Change in dimension × [Original dimension]^-1 . . . . . (1)

The dimensional formula of length = [M⁰ L¹ T⁰] . . . . . (2)

On substituting equation (2) in equation (1) we get,

Strain = M⁰ L¹ T⁰ × [M⁰ L¹ T⁰]^-1 = [M⁰ L⁰ T⁰]

Therefore, the strain is dimensionally represented as [M⁰ L⁰ T⁰] = Dimensionless Quantity.
