Need $15\mathrm{.}12$ but using the beam in $15\mathrm{.}11$

$15\mathrm{.}11$ Compute the maximum deflection of a $10-$in$.-$by$-14-$in$.$ simply supported solid rectangular redwood $($S$4$S$)$ beam. The span length is $15$ ft and the beam is subjected to a uniformly distributed load of $1000l\frac{b}{f}t.$ The allowable deflection is $\frac{1}{300}$ of the span length. Is the beam satisfactory?

$15\mathrm{.}12$ Compute the maximum deflection for the beam of Problem $15\mathrm{.}11$ if the loading consists of one concentrated load of $5000$ lb at midspan instead of the uniformly distributed load. The allowable deflection is $\frac{1}{300}$ of the span length. Is the beam satisfactory?
