Hi, I've got a little problem with a bending moment question.
Here it is (really sorry for the bad diagram!)

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:

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.
