The compound bridge girder shown is to be analyzed using highway moving loads, consisting concentrated and uniformly distributed loads.

At what length of the beam should the uniform highway load be applied to produce maximum reaction at $C?$

A$.8m$

C$.18m$

B$.14m$

D$.22m$

What is the maximum ordinate of the influence diagram for maximum reaction at $D?$

A$.0\mathrm{.}4$

C$.1\mathrm{.}4$

B$.1\mathrm{.}0$

D$.1\mathrm{.}8$

What is the maximum reaction at $D$ for a $20k\frac{N}{m}$ highway uniform load and a concentrated of $10kN?$

A$.184kN$

C$.252kN$

B$.190kN$

D$.266kN$
