or the instantabout the point hd, the resultant of q and Re must passthrough hd- Therefore draw 1, 4 parallel to Ghd and 3, 4parallel to Re to meet in 4; then Re = 3, 4. In the usual case of this mechanism, Fa acts at C at right angles to 0 C; we can then take moments about hd, and we shall have F„… … Fig. 78. Application to Quick-return Motion.—We do not oftenrequire to find all the instantaneous centres for a mechanism STATIC FORCES IN MECHANISMS 137 but it is interesting to trace them out, and we will do so for the quick-return motion, which we have already considered. Referring to Fig. 78,…
