\page inertia_page Inertia
|
|
|
|
This operation returns the axial moments of inertia for the selected geometrical object.

|
The table displays:
|
|
- 3*3 matrix of its own moments of inertia (in cells <b>i:j</b>) and
|
|
- the main (principal) moments of inertia <b>Ip1</b>, <b>Ip2</b> and <b>Ip3</b>
|
|
|
|
\note The matrix of inertia is returned in the central coordinate
|
|
system (G, Gx, Gy, Gz) where G is the centre of mass of the system
|
|
and Gx, Gy, Gz the directions parallel to the X(1,0,0), Y(0,1,0), Z(0,0,1)
|
|
directions of the absolute cartesian coordinate system.
|
|
|
|
\note There is always a set of axes for which the products of inertia
|
|
of a geometric system are equal to 0. These axes are the principal
|
|
axes of inertia. Their origin is coincident with the center of mass
|
|
of the system. The associated moments are called the principal moments
|
|
of inertia. The principal axes are not reported by this functionality.

\note This dialog supports navigation through the selectable objects (in OCC 3D viewer only):
|
|
- Scroll mouse wheel with pressed \em Ctrl key or press \em "S", \em "P" keys when input focus is
|
|
in the viewer to navigate between selectable objects.
|
|
- Press left mouse button to select an appropriate object to the dialog box.
|
|
.

For more details, please refer to the \em "Functionality common for OCC and VTK viewers" chapter
|
|
of the GUI module's documentation.

|
|
|
<b>TUI Command:</b> <em>geompy.Inertia(Shape),</em> where \em Shape is
|
|
a shape for which the own matrix of inertia and the main (principal) moments
|
|
of inertia are returned.
