When they are in opposite phase or differby half a period the resultant is also a straight line (e) inclinedin the opposite direction. For other differences of phase the path SIMPLE HARMONIC… … Fig. 17s. Fig. 176. periods as 1:2, 1:3 and 2:3; the values of 8 indicate the phaseof the faster, when the phase of the slower is zero. These curves may be conveniently illustrated by a double pen-dulum as in Fig. 175. The effective length for vibrations in theplane of the paper is PB, at right…
