The section has an area of A = 56165 mm2 and moment of inertia about the x-axis of Ix = 854.2 ×106 mm4.
Determine the moment of inertia, ICx , of the section about its centroidal x-axis.
Determine the moment of inertia, Ix2 , about the horizontal axis defined by the line y = 40 mm and find the radius of gyration, rx2 , about this same axis
