In terms of the coordinate system shown, the moments and product of inertia of the cross section are

In terms of the coordinate system shown, the moments and
product of inertia of the cross section are Iy =
4.633E_6 m4, Iz = 7.158E_6 m4,
and Iyz = 4.320E_6 m4. The beam is subjected
to a bending moment about the  axis. Draw a sketch
indicating the location of the neutral axis.
