Cuspidal Envelope Rosettes
First Paragraph: | A point P moves in the line segment EG, Fig. 1, with simple harmonic motion of p cycles, while this segment makes q revolutions about A with uniform angular speed. Moritz has exhaustively treated the ...
Stereoscopic Harmonic Curves
First Paragraph | All professors of physics are fond of harmonic curves. Many even seem to consider it a duty, as far as their circumstances permit, at one time or another to construct a machine and draw some of these ...
Concerning a New Method of Tracing Cardioids
First Paragraph: | A cardioid may under certain conditions be traced by a point when its motion is the resultant of a rectilinear simple harmonic movement and a uniform angular one of the same period. The harmonic motion ...
First Paragraph: | The rose, rosette, rosace, Rosenkurve or multifolium, or whatever other name it may have, is a periodic polar curve whose equal sectors may have any angular magnitude. Its general equation, as usually ...
First Paragraph: | One way of drawing a cardioid is to make a pen start in phase 90° from the center of a disk and move along a radius with simple harmonic motion, while the disk revolves with a uniform angular speed of ...
