To prepare a wide flange beam for use as a column, two steel plates are welded to the flanges of the beam. Note that the horizontal centroids of the plates align with the horizontal centorid of the wide flange. Calculate the Moment of Interia for the composite shape about both centroidal axes, to determine the weaker axis of the composite section
