A company plans to make a series of three channelshaped beams by rollforming them from flat-sheet aluminum. Each channel is to have the same outside dimensions as shown in Figure, but they will have different material thicknesses, 0.50, 1.60, and 3.00 mm. For each design, compute the moment of inertia with respect to the horizontal centroidal axis and the location of the flexural center, measured from the left face of the vertical web.
