Question 1 [25 Marks) A beam is undergoing bending deformation, whose cross-section is shown in Figure Q1. a) Determine the cross-sectional properties lxx, lyy 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. 2 2 h 2 С X M 2 3 h 2 Figure Q1
