Use the ultimate design method to estimate the moment capacity $($Mn$)$and the maximum ultimate load the beam shown in the figure below can carry. The length of the beam: $3\mathrm{.}0$ m$,$ cross$-$section of the beam $0\mathrm{.}6$ m $*0\mathrm{.}6$ m$,$ reinforced with $725$ mm $($As$=3434$ mm$2),$ the effective depth $=550$ mm$,$ fc $=28$ MPa, fy $=440$ MPa, consider $=0\mathrm{.}9.$ The maximum moment at the face of the support $=($WuL$2)/6$
