rgy of a Rigid Body Rotating About a FixedAxis. — Suppose the rigid body A, Fig. 101, to rotate aboutan axis through the point 0, at right angles to the plane ofthe paper. Consider the kinetic energy of an element ofmass dm at a distance r from the axis. If v denotes thevelocity of the element and… … Fig. 101. where / is the moment of inertiaof the body about the axis ofrotation. Comparing the expression forthe kinetic energy of rotationwith the expression for the kineticenergy of translation we observethat moment of inertia plays thesame role in motion of rotation as mass, the Unear…
