Question

Take a = 1.0 cm.

Determine the location of the cross section centroid. Given the coordinates of the lower-right corner of the cross section in the Cartesian coordinate system with origin at the centroid, vertical y axis (positive upward) and horizontal z axis (positive to the left). Find the moments of inertia, Iyy, Izz and Iyz with respect to the centroidal coordinate system. Find the principal moments of inertia II and III and the orientation of the principal axes. Identify the orientation of the principal axes associated with II in terms of the angle alpha that it makes relative to the positive y axis.
