Art. 30 133 Since cos 9 = sin (d -\- ^ir), v = m sin (5 + § tt). This formula for v sug-gests an easy method for drawing a v-d graph, showing how the velocityvaries with d, and hence with /. First we draw an auxiliary circle with radiusequal to 2 Trn according to any convenient scale; divide the… … Fig. 236 extension of the horizontal diameter we lay off oT to represent 360°, and sub-divide this into the same number of equal parts (sixteen), numbering as shown;then 01, 02, etc., represent 6 = 22^°, 6 = 45°, etc. Finally we project pointso, I, 2, etc., of the circle toward the right to meet…
