$6\mathrm{.}2$ A cantilever beam with a rectangular cross section, $5cm10cm$ which is built$-$in in a tilted position, carries an end load of $45kgf(441N),$ as shown in Fig. $6\mathrm{.}33.$ Calculate the maximum flexural stress at the built$-$in end and also locate the neutral axis. The length of the cantilever is $1\mathrm{.}2m.$
