For calculating the moment of inertia of a lamina about an axis perpendicular to the lamina we use the perpendicular axis theorem which states that"The moment of inertia of a plane lamina about an axis perpendicular to the plane of the lamina and passing to its centroid is equal to the sum of the moment of inerta about two mutually perpendicular axis passing through the centroid and in the plane of the lamina"
Does this moment of inertia of the lamina about an axis perpendicular to the plane of the lamina have a physical significance by itself or is use only as an aid in calculating the moment of inertia of the lamina about axis which lie in the plane of the lamina??
