A bridge is supported by a pin and rollers at A$,$ C$,$ F$,$ and G$.$ Joints D and E are hinges. Location $\backslash ($ B $\backslash )$ is at the midpoint of span $\backslash ($ A C $\backslash ).$

A$.(15$ points$)$ Sketch the influence line for moment at location B$.$

B$.(10$ points$)$ Use the influence line for moment at location B to determine the extreme bounds of positive and negative moment $($using the typical beam sign convention with positive moment causing compression in the top of the beam$)$ that could be induced by a live load of $\backslash (\backslash$mathbf$\{0.75\}\backslash$mathbf$\{$~ k i p s ~ $/$ ~ f t $.$ ~ $($ N o t e ~ t h a t ~ l i v e ~ l o a d s ~ m a y ~ b e ~$\}\backslash )$ placed anywhere on the structure.$)$ Sketch the loading pattern that corresponds to your value for each case.

C$.($Extra Credit: $+5$ points$)$ What is the maximum moment $($in units of k $-$ ft $)$ that will develop on span FG when subjected to an H$20-44$ truck? $($see below, and note that axle spacing is $14$ ft $.)$
