Using the M$$ller$-$Breslau Principle, draw qualitative influence lines for the vertical reactions at supports A

and B$,$ the bending moment at point B$,$ and the shear and bending moment at point C of the beams shown

below. Also, show the arrangements of a uniformly distributed downward live load W$\_($l$)$ to cause the maximum

upward reactions at supports A and B$,$ the maximum negative bending moment at B$,$ the maximum negative

shear at C$,$ and the maximum positive bending moment at C$.$
