Consider a point P, Fig. 41,moving uniformly around a circle of radius r at a speed of n IOO ELEMENTS OF MECHANICS. revolutions per second,… … Fig. 42. Frequency. The number of vibrations, or cycles, per second iscalled the frequency oi the oscillations of the point P; this is, ofcourse, equal to the number of revolutions per second of thepoint P. Period. The time required for the particle to complete onewhole vibration, or cycle, is…
