A beam having a tee-shaped cross section is subjected to equal 18 kN-m bending moments, as shown. Assume b= 110 mm. t= 20 mm, d = 150 mm, tw = 40 mm. The cross-sectional dimensions of the beam are also shown. Determine (a) the centroid location (measured upward from the bottom), the moment of inertia about the z axis, and the controlling section modulus about the z axis. (b) the bending stress at point H (positive if tensile and negative if compressive). (c) the maximum bending stress (positive if tensile and negative if compressive) produced in the cross section. by H M M Answers: (a) y = 1₂ = S = (b) OH = (c) Omax = Mi M X N Cross section mm (10%) mm4 (10³) mm³ MPa MPa
