A D B, the tie D C sustains the weight from G to H : represent-ing this by the length D C, for convenience one half of G H, anddrawing C M parallel to D B, and M N parallel to A B, the latterrepresents the tension upon A B. Again, in the system A E D F Bthe central tie D C holds the weight from Z… … parallel to A B, M N shows the tension on G C from the braceD G. So also making E N equal to X C, or otherwise to X Zplus half of Z Z, and drawing M N parallel with A B, M Nrepresents the tension upon A G from the brace A E. The ON THE STRAINS IN GIRDERS. I85 sum of the tensions M N and M N is…
