shear and moment diagram

226819270_618821029112373_4751769035499057248_n.jpg A. determine Wo B. Draw the shear and moment diagrams and specify the numerical values at all change of loading positions & at all points of zero shear. C. determine the maximum shear and maximum moment.

UPDATE
I did not see right away that the system is supported all throughout. I now appreciate the wisdom of this problem after I saw it. I will edit my response below to reflect the reaction that will be distributed from point A to point D. For now, I have something I need to finish, so I will be back to this as soon as I can.
