Irfor $($ve $2)$ Draw qualitative influence lines for the vertical reactions $R_8,R_{DU},R_{DE},R_P$ the bending moment $M_5,M_5$ and the shear $V_1,V_1$ of the beam shown in Fig. Also, shown the arrangements of a uniformly distributed downward live load $W_2$ to cause the maximum positive reactions at all $.R_{DF},R_5),$ the maximum negative bending moment $M_R,M_0$ and the maximum positive shear $V_1,V_r(25)$
