The Spring-Force FB element has three symbols' in the graphic-area:

Symbol 11s-red: Spring-Force FB - see below Spring-Force FB connectors
Symbol 22s: Spring 'shape' between the spring's anchor-points
Symbol 33s: Dimension between the spring's anchor-points.

Spring-Force FB1s connectors:


Top: Distance, Velocity Acceleration between the spring's anchor-points.
Bottom: Force, Force-X, Force-Y between the spring's anchor-points.


Use a 'function-map' of data-values to represent a force between the Spring's Anchor Points

The map of Force-Values must 'pass through' a Maths FB to convert the units to Newtons.
