AW 200 ( 41.7 wide-flange beam (see Table E-1(b).
Appendix E) is simply supported with a span length of 2.5 m (see figure). The beam supports a concentrated load of 100 kN at 0.9 m from support B.
At a cross section located 0.7 m from the left-hand support, determine the principal stresses (1 and (2 and the maximum shear stress tmax at each of the following locations: (a) the top of the beam, (b) the top of the web, and (c) the neutral axis.
