Figure 6-3: For the hollow tube section shown in the figure below, determine the A) location of the horizontal centroidal axis
=
in. B) the magnitude of the moment of inertia of the shape with respect to the horizontal centroidal axis using the parallel axis theorem
=
i^(4)
C) the section modulus with respect to horizontal centroidal axis to the outermost top surface of the cross-section is in
^(3)
and to the outermost bottom surfaces of the section is
in^(3)
Note: Take the reference axis to be at the base of the hollow tube section.
