Question 2 (70 marks):

The beam section is symmetrical about its centroidal y axis, Find the x and y coordinates (x_{bar} and y_{bar}) of the centroid of the beam cross-section, relative to coordinates (0,0).

Find the moments of inertia, I_{TF} of the top flange, I_{web} of the beam web and I_{BF} of the bottom flange, all **about C_{x}**.

Find the moments of inertia, I_{Cx} and I_{Cy}, of the beam-section about its centroidal axes

Solution:
