PartialRigid

Models a massless, rigid connection of a defined length between two translational 1D flanges.

This partial component defines an ideal rigid bar of length L that connects two translational 1D mechanical flanges, flange_a and flange_b. The component's position is characterized by the absolute coordinate s of its center point. The positions of the flanges are then kinematically constrained relative to this center point and the length L. The key equations governing these positions are:

$$flange\mathrm{\_}a.s=s-\frac{L}{2}$$$$flange\mathrm{\_}b.s=s+\frac{L}{2}$$

This also implies that the distance between the flanges is fixed:

$$flange\mathrm{\_}b.s-flange\mathrm{\_}a.s=L$$

As a partial component, it is intended to be used as a base for other, more complete components.

"""
Models a massless, rigid connection of a defined length between two translational 1D flanges.

This partial component defines an ideal rigid bar of length `L` that connects two
translational 1D mechanical flanges, `flange_a` and `flange_b`. The component's
position is characterized by the absolute coordinate `s` of its center point.
The positions of the flanges are then kinematically constrained relative to this
center point and the length `L`. The key equations governing these positions are:

math flange_a.s = s - \frac{L}

math flange_b.s = s + \frac{L}

This also implies that the distance between the flanges is fixed:

math flange_b.s - flange_a.s = L

As a `partial component`, it is intended to be used as a base for other, more complete components.
