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 bending$-$

moment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO

exercise.

Determine the shear force acting at

$1)$ x $=11\mathrm{.}0+$ ft $($i$.$e$.,$ just to the right of C$)$

$2)$ x $=22\mathrm{.}0+$ ft $($i$.$e$.,$ just to the right of E$)$

$3)$x $=16\mathrm{.}5-$ ft $($i$.$e$.,$ just to the left of point D$)$

$4)$ x $=16\mathrm{.}5+$ ft $($i$.$e$.,$ just to the right of point D$)$
