20 lbs. rolled joist would be suitable. Inserting the values for this 45 72 section, we liave^— + j^^ = 0-7G + C-24 = 7, as required. If the ends of the girder were not rigidly fixed, the maximum bending moment WL 4 X 20 . would be -^ = —7— =20 ton-ft. instead of 6 ton-ft., and would require a… … r/g./63 -m w ^ V-\ as Fig. 86, and with uniform width of section this would be the theo-retical elevation to give to the cantilever. Practical considerations,however, lead us to the modification of shape shown in Fig. 161. Thesection of the cantilever has unequal flanges like a cast-iron…
