e Fat B and — i^atB give an equal and opposite resultant along CF. These two resultants destroy each otherand leave nothing but thecouple formed by F at A and■ —F at B, which is thereforeequivalent to the originalcouple. Any other displacement ofthe couple in its plane, or to aparallel plane, can… … —+—c yd STATICS. [131- 131. The effect of a couple is not changed if its force F and itsarm p be changed simultaneously in any way, provided theirproduct Fp remain the same. Let AB=p be the original arm (Fig. 33), F the original forceof the couple; and let AB=p be the new arm. The introduc-tion of…
