Textbook Question
Chapter 16.4, Problem 52P
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 σallow = 24 ksi and the allowable shear stress is τallow = 14 ksi. Assume A is a roller and B is a pin.
