## The theorem of parallel axes states that the moment of inertia of a body about anyaxis is equal to the sum of the moment of inertia of the body about a parallel axispassing through its centre of mass and the product of its mass and the square of thedistance between the two parallel axes. ## Suppose a rigid body is made up of n particles, having masses m1, m2, m3, ... , mn, atperpendicular distances r1, r2, r3, ... , rn respectively from the centre of mass O of therigid body.The moment of inertia about axis RS passing through the point O: 10 years ago

It is very simple..

1. It is used to find the moment of inertia of the axis parallel to that of centre of mass.

2. Its general formula is ( IAB = Icm + Md2 ) .... where AB is the parallel line , and CM is the line passing through Centre Of Mass , d is the distance between the two axis.

This is all parallel axis theorem..
