Ladies and Gents,
Please tell me if I am missing something in this problem. The solution computes the maximum moment at the CENTER of the beam and selects a section based on the plastic moment. (The beam is Fixed-Fixed with both a uniform distrib and a concentrated load at the center, with full lateral support).
However, unless the basic beam formulae have not changed, the real maximum moment is really at the fixed ends.
Am I missing something here? The solution the talks about "from the collapse mechanism shown in part "a"". The is a diagram showing hinge locations...but in my mind this is not the critical area.
Anyone else have thoughts on this problem?
