Infent $2)$ Draw qualitative influence lines for the vertical reactions $R_B,R_{DL},R_{DR},R_F,$ the bending moment $M_K,M_D,$ and the shear $V_L,V_1$ of the beam shown in Fig. Also, shown the arrangements of a uniformly distributed $$ live load $W_L$ to cause the maximum positive reactions at all $,R_{DR},R_F),$ the maximum negative bending moment $M_K,M_D$ and the maximum positive shear $V_L,V_1.(25)$
