Problem
A uniform solid disc of mass 2.0kg and radius 0.40m rotates about an axis that is parallel to its symmetry axis and passes through a point on its rim (a tangent axis).
(a) Find the moment of inertia of the disc about this tangent axis.
(b) Calculate the radius of gyration of the disc about the same axis.
