A reinforced concrete beam has a rectangular cross$-$section with a depth, h$,$ of $30$ inches, and a

width, b$,$ of $18$ inches. The beam is a cantilever beam with a length of $12$ feet. The beam must

be designed for a superimposed uniformly distributed dead load of $1$ kip$/$ft$,$ a uniformly

distributed snow load of $1\mathrm{.}3$ k$/$ft and a point live load applied at the free end of the cantilever

of $20$ kips. Find $M_u$ and $V_u$ for this beam. Please show all work, explanation and details as to how you solved the problem.
