AB - Sept., 1898.] Cambered Brake-Beam. 215 BY IRVING P. CHURCH, C.E., ITHACA, N. Y. By "brake-beam," in this paper, will be understood the trussed beam shown in diagrammatic form in Fig. 3, consist- ing of a prismatic bar or beam AOB, a short post or strut, OD, and two prismatic tie-rods or tension-members, GD and GtD, meeting the post at the joint D. By "cambering" this brake-beam is meant forcing together the extremities B and G (and A and G r) until they meet, and permanently fasten- ing them in this position. In the assumption of this con- strained form the elastic limit is not supposed to be passed in any member. This constrained or "cambered" form is shown by the full continuous lines in Fig. 4, in which the vertical dimensions of the whole frame, and the amount of bending of the bar AOB, are much exaggerated. This state of initial constraint, brought about before the brake-beam is put to use, occasions a certain initial tensile force (To)in each of the tie-rods, and a thrust (Q0) in the post, and subjects the bar .4B to combined flexure and thrust. It is the object of this paper to determine the
