Calculating Moments of Inertia
In order to perform any calculations on a profile, you need to know its moment
of inertia.
To calculate the moment of inertia
1 Start the calculation for the moment of inertia. On the command line,
enter AMINERTIA.
2 Respond to the prompts as follows:
Specify interior point: Click a point inside the profile
Specify interior point: Press ENTER
Is the area filled correctly? (Yes/No)? <Yes>: Press ENTER
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
