Question

Dimensional formula of moment of inertia

Answer 1

Answer:

Moment of inertia is defined as the product of mass of body and square of perpendicular distance from the axis of rotation

I=MR^2

Whereas M is mass of body

R is perpendicular distance of body from the axis of rotation.

SI unit is kg-m^2

Dimensional unit is [ML^2]

Answer 2

The area moment of inertia is a property of a two-dimensional plane shape which characterizes its deflection under loading. It is also known as the second moment of area or second moment of inertia. The area moment of inertia has dimensions of length to the fourth power.
