Simple beam has an overhang

4.5-10 A beam ABC is simply supported at A and B and has an overhang BC (see figure). The beam is loaded by two forces P and a clockwise couple of moment Pa at D that act through the arragement shown.

(a)Draw the shear-force and bending-moment diagrams for beam ABC.

(b)If moment Pa at D is replaced by moment M, find an expression for M in terms of variables P and a so that the reaction at B goes to zero.
Plot the associated shear-force and bending-moment diagrams for beam ABC.
