Figure $6-1$: For the angle section shown in the figure below, determine the

A$)$ location of the horizontal centroidal axis $=$

mm $.$

B$)$ the magnitude of the moment of inertia of the shape with respect to horizontal centroidal

axis using the parallel axis theorem $=$

$m{m}^4$

C$)$ the section modulus with respect to horizontal centroidal axis to the outermost top

surface of the cross$-$section is

$m{m}^3$ and to the outermost bottom

surfaces of the section is

$m{m}^3$

Note: Take the reference axis to be at the base of the horizontal leg of the angle.
