Problem #$3$: Draw the shear and bending moment diagrams. Note that the joint $($B$)$ between the column and beam is considered a rigid joint. Identify the location of maximum and minimum bending moment. Also identify the location of point of inflection $($if any exist$).$ The support reactions at A and D: horizontal support reaction at $A=40k($toward left$).$ Vertical support reaction at $A=6\mathrm{.}25k($downwards$)$; vertical reaction at support $D=42\mathrm{.}25k($upwards$).$
