Not illustrated. 1879 edition. Excerpt: ...resistance to extension, and rigidity of attachment of the respective pieces, it is most natural that the weight should pass up the vertical to the bow; for in this line it meets the most direct resistance or reaction. That is, if we imagine the weight to strain all three of the pieces at once, a slight.yielding, or extension of the two diagonals, will lower the loaded point more than the same amount of extension in the vertical, and hence the weight will be thrown more upon the vertical; and as the vertical, being the shortest member, will stretch least in total amount for the same stress per square inch, the weight will still more be carried by it. Hence the assumption, that the verticals carry the load when it is complete, cannot be far from the truth. 75. Maximum Stresses in Braces.--By deducing a formula for the braces, we shall be enabled to prove a very short construction for obtaining the desired stresses. In finding these stresses, we will avail ourselves of the fact that the horizontal projection of the stress in a brace must equal the difference of the horizontal forces in the two chord-pieces of the panel in which the brace is situated; and we will prove that this horizontal component is a constant quantity when the brace experiences the maximum stress. If the steady load is neglected at present, the polygon A E F G I D B may represent the equilibrium polygon for a complete moving load. If the sides F G, G I, &c, are prolonged until they intersect the vertical through A, the points K, L, M, &c, will be the extremities of the equilibrium polygons for partial loads, extending from B to the successive joints. The distance A K has been proved, in 68, w' I to be when w' = travelling load on one joint. As H will, by...
