This program will calculate the elevation of the centroid, the area
moment of inertia about the centroid and the area of an T-beam given
the dimensions of the beam. The number returned for the centroid is
the elevation above the point y=0 (indicated).

Hopefully that is an informative diagram! Note that the height
goes all the way from the bottom to the top of the beam, not from
inside the top flange.
