Burr, William H. (William Hubert), 1851-1934 · New York, John Wiley & Sons, inc.; [etc., etc.] · leaf 134
- Art. 24. THE THEOREM OF THREE MOMENTS. 103 ference can only be accomplished by the application of acouple to the beam, the forces of the couple being appliedat the two adjacent points of support; the span, conse-quently, will be the lever-arm of the couple. The existenceof equilibrium requires… … Fig. it appears that the force of this couple is equal to thedifference between the actual reaction at either point ofsupport and that foimd by the law of the lever. Thebending caused by this couple may evidently be of anopposite kind to that existing in a beam simply supportedat each end. These…
