A beam is subjected to equal bending moments of magnitude M= 230 N·m. The cross-sectional dimensions are a = 20 mm, b = 44 mm, d = 72 mm, and r = 17 mm. 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 point H. Tensile stress is positive, while compressive stress is negative. (c) the bending stress at point K. Tensile stress is positive, while compressive stress is negative. (d) the maximum bending stress produced in the cross section. Tensile stress is positive, while compressive stress is negative. b U H M. x M. 27
