$"4-47.$ Draw the shear and moment diagrams for each member of the frame. Assume joints $B$ and $C$ are fixed connected."

The correct answers are:

Vmax$=12\mathrm{.}0$ k$,$ Mmax $=72\mathrm{.}0$ k ft on AB$,$

Vmax $=-20\mathrm{.}0$ k$,$ Mmax$=76\mathrm{.}0$ k ft on BC$,$

Vmax $=0,$ Mmax $=0$ on CD$.$
