P$3$: For the beam shown in Figure P$8\mathrm{.}14,$ draw the influence lines for the reactions at A $,B,$ and $F,$ the end moment at $F,$ shears to the left and right of support $B,$ and shear at $E.$

P$4$: Draw the influence lines for RA and the bar forces in members AD$,$ EF$,$ EM$,$ and NM$.$ Loads are transmitted into the truss through the lower chord panel points. Vertical members EN and GL are $18$ ft long, FM is $16$ ft $.$ show the work for p$-3$ and p$-4$ thanks
