Use the graphical method to construct the shear$-$force and bending$-$moment diagrams for the beam shown. Let $a=9\mathrm{.}0ft,b=7\mathrm{.}0ft,c=12\mathrm{.}0ft,d=4\mathrm{.}0ft,w_B=6\mathrm{.}5$kip$\frac{s}{f}t,$ and $w_{CE}=2\mathrm{.}5$kip$\frac{s}{f}t.$ 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.

Calculate the reaction forces $B_y$ and $D_y$ acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown on the free$-$body diagram below. $($Note: Since $B_x=0,$ it has been omitted from the free$-$body diagram.$)$

Answers:

$B_y=$ kips

$D_y=$ kips
