Code restrictions, due to a plaster ceiling, require the maximum displacement not to exceed $\frac{1}{360}$ of the span length. Assume $A$ is a pin and $B$ a roller support. The allowable bending stress for the beam is ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=24$ksi and the allowable shear stress is ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=14$ksi.

Part A

Select the lightest$-$weight A$-36$ steel wide$-$flange beam from Appendix B that will satisfy this requirement and safely support the load.
