What is Parallel axis Theorem ??​

Answer 1

Parallel Axis Theorem

The theorem of parallel axis states that the moment of inertia of a body about an axis parallel to an axis passing through the centre of mass is equal to the sum of the moment of inertia of body about an axis passing through centre of mass and product of mass and square of the distance between the two axes.

Answer 2

Answer:

Parallel axis Theorem

The parallel axis theorem, also known as Huygens–Steiner theorem, or also known as Steiner's theorem.

This theorem is exists to object of any shape.

This theorem states that the moment of inertia of a body about an axis parallel to an axis passing through the centre of mass is equal to the sum of the moment of inertia of body about an axis passing through centre of mass and product of mass and square of the distance between the two axes.

let a be the distance between two axis ,I be the moment of inertia of body ,centre of mass be M and inertia of body is ib

so ,

ib = i + M a^2
