A beam having a tee-shaped cross section is subjected to equal 10 kN-m bending m

Question

A beam having a tee-shaped cross section is subjected to equal 10 kN-m bending moments, as shown. 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.
