highest possibleposition of A is A0, where DB and BA come into onestraight lineZ>i?0^0, and where, therefore, DA0 = DB + BA.Similarly its lowest position is Av where DA^DB + BA.In like manner the limiting positions of B are B\ and B2,where CB1 = CB.2 = CA + AB. Thus to find AQ and Ax describe… … B\B} Note also that A0B0 is normal to the curve at PQ, sincefor this position A0 is the instantaneous centre of rotationof the link. This statement may be tested by trial withthe template, and its truth will then be quite evident.The end A of the link, having come to the limit of itsmovement at A0,…
