Further,from what has immediately preceded, it appears that theforce of this couple is equal to the difference between theactual reaction at either point of support and that found bythe law of the lever. The bending caused by this couple willevidently be of an opposite kind to that existing in a… … Fig. 2. RF is the force of the applied couple; consequently ^7^ =AR + RF and BF= BR ~ {RF= RF) are the reactionsafter the couple is applied. As is well known, lines parallelto CK, drawn in the triangle A CB, represent the bending mo-ments at the various sections of the beam, when the reac-tions are…
