(15%) Problem 2 (Pro 8.11 Textbook modified): Two steel plates (A572, Fy = 50 ksi) are welded together to form an inverted T-beam. Determine the maximum bending stress developed. Also determine

the maximum shear stress at the neutral axis of the cross-section and at the intersection where the stem joins the flange. Ignore the weight of the steel plates. X N.A.
