Problem 5.6-5A simple beam ABis loaded as shown in the figure. Calculate the required section modulus Sif sallow±17,000 psi, L±28 ft, P±2200 lb, and q±425 lb/ft. Then select a suitable I-beam (Sshape) from Table E-2(a), Appendix E, and recalculate Staking into account the weight of the beam. Select a new beam size if necessary. Problem 5.6-4A simple beam of length carries a uniform load of intensity and a concentrated load (see figure).Assuming , calculate the required section modulus .Then select an 200 mm wide-flange beam (W shape) from Table E-1(b)Appendix E, and recalculate taking into account the weight of beam.
