A cantilever beam of W 12 × 14 section and length L = 9 ft supports a slightly inclined load P = 500 lb at the free end (see figure).
(a) Plot a graph of the stress sA at point A as a function of the angle of inclination a
(b) Plot a graph of the angle b, which locates the neutral axis nn, as a function of the angle a. (When plotting the graphs, let a vary from 0 to 10°.) (Note: See Table E-1 of Appendix E for the dimensions and properties of the beam.)
