$($Prob$\mathrm{.}2)$ A simple beam with an overhanging. A uniform distributed load $w$ includes the beam's own weight, the service dead load $w_{1D}=5t\frac{f}{m},$ and the live load $w_L=2t\frac{f}{m}.$ Determine the factored design moment $M_u$ at point $D.$ Use length $L=8m,$ width $b=40cm,$ height $h=70cm,$ effective depth $d=60cm,$ and concrete weight $w_c=2\mathrm{.}4t\frac{f}{m^3}.$

Ans: $M_u=70\mathrm{.}045tf*m$
