Figure Q 1 shows a single-symmetrical section (the top flange is shorter than the bottom flange) of a steel beam. a) Determine the area of the section. b) Based on the y-z axis (given in the figure), determine the centroid of area. c) About the centroidal axes y-z, which are parallel to the y-z coordinate system, determine the second moment of area about y-axis and z-axis by the parallel-axis theorem (see Appendix 3). d) Determine the radius of gyration of the section about y-axis and z-axis.
