Solution to Problem 519 | Flexure Formula

Problem 519
A 30-ft beam, simply supported at 6 ft from either end carries a uniformly distributed load of intensity wo over its entire length. The beam is made by welding two S18 × 70 (see appendix B of text book) sections along their flanges to form the section shown in Fig. P-519. Calculate the maximum value of wo if the flexural stress is limited to 20 ksi. Be sure to include the weight of the beam.
