A beam having a tee-shaped cross section is subjected to equal 12 kN-m bending moments, as shown. Assume b;- 110 mm, t- 25 d- 160 mm, t - 30 mm. The cross-sectional dimensions of the beam are also shown. Determine (2) the centroid location (measured upward from the bottom), the moment of inertia about the zaxis, 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. Cross section
