Mass
Mass moving in 1D space. In Laplace domain with \(s\in\mathbb C\):
\begin{equation*}
f(s) = \frac{e(s)}{M\,s}.
\end{equation*}

Power variables
flux: Velocity \(v\) (m/s)
effort: Force \(f\) (N)
Arguments
- label : str
- Mass label.
- nodes : ('N1', 'N2')
- Nodes associated with the component terminals with positive flux N1->N2.
- parameters : keyword arguments
- Component parameter.
| Key | Description | Unit | Default |

Example
>>> # Import dictionary
>>> from pyphs.dictionary import mechanics_dual
>>> # Define component label
>>> label = 'mass'
>>> # Define component nodes
>>> nodes = ('N1', 'N2')
>>> # Define component parameters
>>> parameters = {'M': 0.01, # Mechanical mass (kg)
... }
>>> # Instanciate component
>>> component = mechanics_dual.Mass(label, nodes, **parameters)
>>> # Graph dimensions
>>> len(component.nodes)
2
>>> len(component.edges)
