he axis ofrotation. The name given to thisdistance is the radius of gyration.It is defined by k in the followingequation: (27) (2m) £2 = ~%mr2. The calculation of k, even for sim-ple cases, is not readily effectedwithout the use of the IntegralCalculus,1 and hence need not bediscussed here.… … Fig. 62. COMPOUND PENDULUM. 93 61. Theorem. — The moment of inertia about any axis is equal tothe moment of inertia about a parallel axis through the center of gravityincreased by the product of the mass of the body by the square of thedistance between the parallel axes. Let G be the center of…
