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 in Figure. 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.
