psi, $n=10).w_D=2\mathrm{.}5\frac{k}{f}t($including self weight$).L=18ft.$ Live load $(P_L=30k)$ is applied

as a concentrated load at the middle of the beam. Sustained live loads of $1\frac{k}{f}t$ is applied for a

duration of $20$ months. Please use the PDF file provided in reading materials section to

determine the bending moments and deflections.
