Question 1 (25 Marks] A beam is undergoing bending deformation, whose cross-section is shown in Figure Q1. a) Determine the cross-sectional properties Ixx, Iyy and Ixy. [9 Marks] b) Determine the direct (bending) stress distribution in the section beam, produced by a positive bending moment, Mx. [16 Marks] The cross-section is anti-symmetric with centroid at the mid-point of the vertical web. No moment is applied about the y-axis, i.e. My = 0. = ку h 2. 2 h 2 G х M h 2 3 h 2 Figure Q1
