Problem 2: the most economical (lightest) W shape to support a uniformly distributed load of 4k/ft (This load includes the weight of the beam) on a simply supported span of 25 ft as shown. Assume the yield stress of the steel to be 50 ksi. The deflection limit (Allowable) is Select 360 w 4 kips/ft 25'-0" R 50 kips RB 50 kips

In Appendix C, see the simply supported beam with
a uniformly distributed load. Be careful with units and the sign
convention. For this calculation, the overhung part of the beam
from C to D can be ignored, and the beam is
treated as a simply supported beam of length
2L1. Be careful with units and the sign
convention.
