$=114-$kip upward, $C_y=144$ below given $w=4$ kip$/$ft$,P_1=0-$kip, $P_2=18-$kip, and the reactions $A_y$

Draw the V & M Diagrams to answer the questions below. Show all the work done to draw them. Show all the work done to draw them. No work shown, no credit. Tip: Draw diagrams using the semi$-$graphical method $($last method learned$).$

Question $13$

A$.$ horizontal line

B$.$ straight line with a positive slope

C$.$ straight line with a negative slope

D$.$ curve of second degree that is convex

E$.$ curve of second degree that s concave

Question $14$

A$.$ curve of third degree, which opens upward

B$.$ curve of third degree, which opens downward

C$.$ horizontal line

D$.$ curve of second degree that is concave

E$.$ curve of second degree that is convex
