mm Position of the center of mass in the reference
system
A, B, C Degrees Orientation of the principal inertia axes
• A: Rotation about the Z axis of the refer-
ence system
The result is a coordinate system named
CS'.
• B: Rotation about the Y axis of CS'
Result: CS''
• C: Rotation about the X axis of CS''
Note: A, B and C are not shown in the dia-
gram.
