Question

Moment of inertia of a solid cylinder about a transverse axis passing through its centre
Please explain how to calculate it.

Answer 1

Calculate moment of inertia through the center of each disc along an axis perpendicular to the plane of discs. This gives moment of inertia of cylinderalong it's axis. Now, use the property that Mx + My = Mz. Meaning, moment of inertia through center of mass along 3 perpendicular axes x, y, z follows this property.
