Question $7$

Use the graphical method to construct the shear$-$force and bending$-$moment diagrams for the beam shown. Let $a=5\mathrm{.}5ft,w=230l\frac{b}{f}t,M_D=6900lb*ft,$ and $P=1100lb.$ Construct the shear$-$force and bendingmoment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise.

Determine the bending moment acting at $x=16\mathrm{.}5-ft($i$.$e$.,$ just to the left of point D$)$
