(a) Draw the influence lines for reactions \(R_{B}, R_{D}\), and \(R_{F}\) of the beam in Figure P12.5 and the shear and moment at \(E\).

(b) Assuming that the span can be loaded with a \(1.2 \mathrm{kips} / \mathrm{ft}\) uniform load of variable length, determine the maximum positive and negative values of the reactions.
