Fig. 2. — In This Case the Mass M, Rotating n Times Per Second, About An Axis O, is Divided Into Numerous Elements or Small Parts at Various Radii from O. Knowing the Kinetic Energy of Each Part, the Whole Kinetic Energy of the Mass is Easily Determined by Taking a Summation of the Individual Quantities.
