6. For the cantilover beam with the distributed load shown, what is the moment at the support? (A) \( 240 \mathrm{lbf} \) (B) \( 480 \mathrm{lbf}- \) in (C) \( 960 \mathrm{lbf}-i n \) (D) \( 2880 \mathrm{lbf}-i \mathrm{n} \) (E) \( 3480 \mathrm{lb} \)-in 7. Determine the area moment of inertia of the following beam around the \( x \) centroidal axis. All sections are 1 inch wide.
