Use thesimplified expression for computing K, but still verify that it applies.The average stress in the top flange can be determined by an My/I calculation, as opposed to a P/Acalculation from previous problems. Compute y based on the mid-depth of the top flange.Ignore the "fillets" (i.e., the rounded portions of the I-section) when calculating the moment of inertia, I.
