a motion of rotation will now begiven. § 159.—Consider an element m of a body, situated at adistance r from an axis of rotation L M. Denote by V thevelocity which it has at any in-stant, and by p its weight, m its Fig. 100. pmass = —, Then will its living force be — . V2 or m V2. If S denote the… … t t (59); but we have seen that, in any motion whatever, thevelocity is equal to the space described, during a veryshort interval of time, divided by this interval, hence t& = V, = Vu relation ofangular toabsolute velocity; in which Vx is the velocity of the point at the units dis-tance from…
