class Mass_Properties(Data):
"""
A class containing mass and inertial properties for physical components.
Attributes
----------
mass : float
Total mass of the component, defaults to 0.0
volume : float
Volume of the component, defaults to 0.0
center_of_gravity : ndarray
3D coordinates [x, y, z] of the component's center of gravity,
defaults to [0.0, 0.0, 0.0]
moments_of_inertia : Data
Collection of inertial properties
- center : ndarray
Reference point for inertia calculations [x, y, z],
defaults to [0.0, 0.0, 0.0]
- tensor : ndarray
3x3 inertia tensor about the reference point,
defaults to zero matrix
Notes
-----
The Mass_Properties class provides a standardized structure for tracking mass-related
properties of components. It includes:
* Basic mass and volume
* Center of gravity location
* Full inertia tensor definition
* Reference point specification
