Question

state and Prove the theorem of parallel axis about moment of inertia???​

Answer 1

Perpendicular Axis Theorem

For a planar object, the moment of inertia about an axis perpendicular to the plane is the sum of the moments of inertia of two perpendicular axes through the same point in the plane of the object. The utility of this theorem goes beyond that of calculating moments of strictly planar objects. It is a valuable tool in the building up of the moments of inertia of three dimensional objects such as cylinders by breaking them up into planar disks and summing the moments of inertia of the composite disks.

Answer 2

hey mate , here's your answer....



•Parallel Axis Theorem:-

The theorem determines the moment of inertia of a rigid body about any given axis, given that moment of inertia about the parallel axis through the centre of mass of an object and the perpendicular distance between the axes.

This is the proof of Th. of Perpendicular and parallel axis:-
