[PLAIN]http://img249.imageshack.us/img249/7237/bendingshearsolution.jpg
When 2<x<5:
I do not understand how to obtain the graph.
Shouldn't the graph be from 0<x<5, since it includes the 2m and reaction force at A?
I also do not know how to obtain the (x-2).

I do not understand how to obtain the (7-x) or (9-x) in the moment equilibrium equation.
Hope someone can help.
Cheers,
