Chapter 8, Reserve Problem 045 (GO Tutorial) A beam having a tee-shaped cross section is subjected to equal 13 kN-m bending moments, as shown. Assume b = 95 mm, ty = 25 mm, d = 165 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. Cross section Answers: (a) y = mm I: = |(105) mm4 S= (10) mm3 (b) GH = MPa (c) Omax = MPa
