Resistance = V/I Dimensional formula for V ML2T -3A -1 Dimensional formula for I A Dimensional formula for R= ML2T -3A -1 / A = ML2T -3A -2
Resistance = V/I Dimensional formula for V ML2T -3A -1 Dimensional formula for I A Dimensional formula for R= ML2T -3A -1 / A = ML2T -3A -2
y(young's modulus of rigidity)=stress/strain now strain is dimensionless hence y=stress y=M L-1 T-2
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
The formula for calculating strain is: Strain Change in length / Original length. The formula for calculating stress is: Stress Force applied / Cross-sectional area.
The dimensional formula for angular velocity is T-1, where T represents time.
The formula to calculate total strain is: Total Strain Elastic Strain Plastic Strain. Elastic strain is the initial deformation of the material under load, while plastic strain is the permanent deformation after the material reaches its yield point.
The dimensional formula of depression is that it has the same dimensions as pressure, which is force per unit area. Thus, the dimensional formula of depression is [ML^-1T^-2].

The true stress formula is: True Stress Load / Area The true strain formula is: True Strain ln(Length after deformation / Original Length)
