The beam shown will be constructed from a standard steel W-shape using an allowable bending stress of 68.4 ksi. Assume P = 55 kips, L₁ = 5.7 ft, and L₂ = 17.1 ft. (a) Determine the minimum section modulus required for this beam. (b) From the table below, select the lightest W shape that can be used for this beam. (c) What is the total weight of the steel beam itself (i.e., not including the loads that are carried by the beam)?
