The coordinates of the centroid and the moment of inertia along the
principle axes are displayed on the command line, as follows:
Coordinates of centroid (in user coordinates):
X coordinate: 228.071933 Y coordinate: 150.027674
Moments of inertia along principal axes:
I1: 2.359e+004 I2: 1.4095e+004
Axis angle for major moment (I1): 5.3
Define the direction of the loads. They must be in one plane.
