Use the graphical method to construct the shear$-$force and bending$-$moment diagrams for the beam shown. Let a$=4$ft$,$b$=7$ft$,$c$=4$

ft and w$=8\mathrm{.}5$kip$($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 A$\_($y$)$ and C$\_($y$)$A$\_($x$)=0,$ it has been omitted from the free$-$body diagram.

Part $2$

Determine the shear force acting at each of the following locations:

$($a$)$ x$=0+$ftA x$=4$ft

$($c$)$ x$=11-$ft $($i$.$e$.,$ just to the left of support C $)$

$($d$)$ x$=11+$ft $($i$.$e$.,$ just to the right of support C $)$

When entering your answers, use the shear force sign convention.

Answers:
