Determine the bending stress for the $"$L$"$ section $($Web$=5$cm$,$ Flanges$=3$cm$)$ Cantilever beam $0\mathrm{.}5$ m long and $0\mathrm{.}5$ cm thickness as shown in figure. A force $P=1KN$ is acting on free end cross section. $($Take; $I_z=9\mathrm{.}44c{m}^4,I_y=2\mathrm{.}58c{m}^4,I_{yz}=2\mathrm{.}813c{m}^4).$
