minus sign whenthe velocity for the first half of the period is indicated. 63. The Value of the Velocity at any Point. With the aid of Fig. 44, the actual value which the fraction ^^ assumes for any position of p may at once beobtained. Here PL representsthe velocity of p, or v, whilePM and PN… … Fig. 44. Value of velocity iu liar-Dionic motiou. G6 HARMONIC MOTION. that is, — = — sin V or Ck = — V sin $. From this it is seen that v^, the velocity of p, is always afractional partof v, the velocity of P, and, moreover, that it issuch a fractional part as is represented by — sin 0. The…
