Asimply supported 25-foot long w33x141 beam (fy = 50ksi) supports a uniformly distributed service load. if the live load is twice the dead load, what is the maximum total service load that can be supported. don’t forget to factor in self weight. you can assume that the beam is compact and that it has continuous lateral support.
