Flexible connectors let you connect two bodies in a compliant way. In contrast to
Joints, which are rigid connectors, flexible connectors do not absolutely prohibit any part movement and, therefore, do not remove any
Degrees of freedom from your model. Flexible connectors do typically resist movements between parts (see
Part (also called Bodies)), however, by applying spring and damper forces to the connected bodies. These forces are proportional to the displacement and rate of change in displacement between two parts, respectively.
