a$)($uniaxial loading of composite bar$)$ The composite bar in Part II $(3)$ is subject to a tensile axial force$($in x$-$direction$)$ of $20$ kN $.$ The resultant force passes through the intersection point of the two neutral axes so that the composite bar remains straight$($no bending$).$ Determine the stress in the steel bar. $($Equilibrium $+$ compatibility $$ forces in each bar$)$

b$)$ Now the force is applied at the lower right corner of the end of the bar as shown below $($shown right$).$ It is statically equivalent to a resultant force passing through the intersection of the two neutral axes, two moments about $y-$ and $z-$axis. Use the results in a$)($above$)$ and Part II$(3)$ to calculate $M_y,M_z$ and the combined stress at point A

Please draw a freebody diagram to better explain. If possible also use the principle of superposition for combined stress formula. Need ASAP!!!
