Vedclass · Answer

(C) The moment of inertia $I$ of a body is given by $I = \sum m_i r_i^2$. By concentrating the mass $M$ at the rim (at a distance $R$ from the axis of rotation),the radius of gyration is maximized. Since $I = MR^2$ for a ring-like structure,placing the mass as far as possible from the axis of rotation significantly increases the moment of inertia. $A$ higher moment of inertia allows the flywheel to store more rotational kinetic energy and resist changes in its rotational speed,which is the primary function of a flywheel.

$A$ flywheel is constructed such that its entire mass is concentrated at the rim because:
