the calculation will be still the same; for the moment of inertia P . of the solid P will as before be A:—, k being the principal radius of gyration as measured from the geometrical axis. Thus in fig, 121,let P denote a sphere whose radius is 3 feet, and weight 500 lbs. ;the weight W:=50 lbs., and… … ILLUSTRATIVE PROBLEMS. 207 and let it be required to determine the time in which the weight Wwill pass through any given space, as, for example, 50 feet.
