A bar assembly is subjected to a force as shown below. The diameter of the bars is $0\mathrm{.}1$ m $.$ The origin of the coordinate system $x-y-z$ is at the center of the bar. Determine the internal loading $(F_x,F_y,F_z,M_x,M_y,M_z)$ on the cross$-$section at the wall. Calculate all the stress components $({}_x,{}_y,{}_z,{}_{xy},{}_{yz},{}_{zx})$ at location $A(0,0,0\mathrm{.}05m).$ Identify the directions of the stresses on the stress element.

$d=0\mathrm{.}1m$

$r=0\mathrm{.}05m$

$A=7\mathrm{.}85{10}^{-3}{m}^2$

$,I=4\mathrm{.}9{10}^{-6}{m}^4$
