Example 1: A beam with an inverted tee-shaped cross section is subjected to positive bending moments of Mz = 5 kN-m. Determine: (a) the centroid location, the moment of inertia about the z axis, and the controlling section modulus about the z axis. (b) the bending stress at points H and K. State whether the normal stress is tension or compression. (c) the maximum bending stress produced in the cross section. State whether the stress is tension or compression. 10 mm
