Question 3 (45 marks):

The section has an area of *A* = 56165 mm^{2} and moment of inertia about the *x*-axis of I_{x} = 854.2 ×10^{6} mm^{4}.

Determine the moment of inertia, I_{Cx} , of the section about its centroidal *x*-axis.

Determine the moment of inertia, I_{x2} , about the horizontal axis defined by the line *y* = 40 mm and find the radius of gyration, *r _{x2}* , about this same axis

Solution:
