The beam supports the loading shown. Code restrictions, due to a plaster ceiling, require the maximum deflection not to exceed 1>360 of the span length. Select the lightest-weight A-36 steel wide-flange beam from Appendix B that will satisfy this requirement and safely support the load. The allowable bending stress is sallow = 24 ksi and the allowable shear stress is tallow = 14 ksi. Assume A is a roller and B is a pin.
