Chapter 5, Problem 5.10.9P
A simple beam with an overhang supports a uniform load of intensity q = 1200 lb/ft and a concentrated P = 3000 lb load at 8 ft to the right of A and also at C (sec figure). The uniform load includes an allowance for the weight of the beam. The allowable stresses in bending and shear are 18 ksi and 11 ksi. respectively.
Select from Table F-2(a), Appendix F, the lightest I-beam (S shape) that will support the given loads.
Hint: Select a beam based upon the bending stress and then calculate the maximum shear stress. If the beam is overstressed in shear, select a heavier beam and repeat.
