Chapter 9, Problem 9.10.5P

A weight W = 4000 lb falls through a height h = 0.5 in, onto the midpoint of a simple beam of length L = 10 ft (see figure).

Assuming that the allowable bending stress in the

beam is

= 18,000 psi and E = 30 x 10* psi,

select the lightest wide-flange beam listed in Table F-l(a) in Appendix F that will be satisfactory.
