Select an economical A 36 steel wide flange section as a beam to carry a combined uniform distributed load of 10,000 plf and a 70-kip concentrated load placed at mid-span. The beam's clear span $$=30^{?}$$, with adequate lateral support. $$F_b$$ and $$F_v$$ are $$0.6F_y$$ and $$0.4F_y$$ respectively, where $$F_y$$ is the yield strength of A36 steel. The deflection requirement is $$\mathrm{D}<$$ $$\mathrm{L}/240$$. (Full credit $$=3\mathrm{pts})$$. Hints: 1) You do not need to consider the beam's self-weight in this question. 2) Use the textbook Appendix 1 for the wide flange sections. 3) The Elastic Modulus, E, for A36 steel is $$29\times 10^6$$ psi. 4) We discussed the yield strength of A36 steel in session 3. 5) Do not forget to perform bending, shear, and deflection check.
