Hi, I've got a little problem with a bending moment question. Here it is (really sorry for the bad diagram!) http://img474.imageshack.us/img474/7844/help15eu.jpg R1 and R2 are reactional forces, which using moments I have calcualted to be: R1=110kN R2=141kN Section A of the beam is a mild steel beam, section B can be presumed to have infinite strength (i.e. all of the bending is taken by section A). The value of 1000 x 9.81 is the weight of section A, do I take this into account in the bending moment diagrams? How do I go about drawing the diagram for this, here are two possibilities: http://img469.imageshack.us/img469/4135/help25cc.jpg In (b), I have said that section B can be treated as a wall, with a moment produced by the forces to the left of the wall. I need to calculate the maximum bending stress in section A. Any help would be amazing! Hope I've made any sense, if you need any more info, just ask. Thanks a lot, Oli.
