A beam of channel section (C8x11.5) is subjected to a bending moment M of 18 kips-in at an angle of 18 degrees from the z-axis (see figure). Determine the magnitude of the orientation of the neutral axis measured from the +z-axis. C8x11.5 has the following dimensions & properties: d = 8.0 inches, b = 2.26 inches, and t = 0.571 inch, Iy = 1.32 in4 and Iz = 32.6 in4. Answer must be in degrees, up to 1 decimal place.
