A moment M acts through the centroid of theat an inclination angle 6 10°. The depth of the web is h, 9a. (a) Determine the orientation of the neutral axis,

and show the neutral axis on a sketch of the cross section. (b) Determine the maximum tensile flexural stress acting on the cross section, and compare this with the maximum tensile flexural stress the beam would T-section in Fig.experience if theta = 0°. Express your answers in terms of M and the dimension a.
