ng motion in the slot is the resultant motion of thepoint. Hence, if PN be drawn perpendicularly to the directionof the slot, the instantaneous centre of the block must lie in thisline, and must therefore be the point of intersection N with BAproduced, so that the block, at the instant, may be… … Fig. 171. meanings as in Fig. 168. The angular motion of the block aboutN must be the same as that of PC about P, and, for a slightdisplacement, must be SO, and the corresponding angular dis-placement of AB about A is Si/i; from which it follows that thearc BB is equal to either AB.
