e centre.Hence it is immediately apparent, from the above property 28 CJmrcJi [J.F. I., of harmonic motion, that if a circle be described with O as a,centre and radius equal to r, it will be a velocity-distancecurve for the harmonic motion ; with a scale-number 7t =c ^ r, since the radius OE (= OD… … Fig. 3.aside from its simplicity of construction, the circle has apeculiar advantage, as will be seen, in representing the timeof reaching any point.) The above circle being drawn, the subnormal ti for anypoint m of the path, is equal to the abscissa s with its signchanged, whence the acceleration…
