The resultant moment M acts through the centroid of the aluminum strut, inclined as shown. 

(a) Determine the orientation of the neutral axis and show the neutral axis on a sketch of the cross section.

(b) Determine the location and magnitude of the maximum tensile and compressive flexural stresses acting on the cross section.

(c)  Compare the results of (a) and (b) with the maximum tensile flexural stress the beam would experience if there had been no inclination of the moment, i.e., M_z = -660 N.m.
