Detailed Description

A constant force f (a signed scalar) which acts along the line between two points, specified as a station on each of two bodies.

A positive force acts to separate the points; negative pulls them together. The force magnitude is independent of the separation between the points. This force does not contribute to the potential energy, so adding it to a system will cause energy not to be conserved. It is an error if the two points become coincident, since we are unable to determine a direction for the force in that case.

Parameters:

forces	the subsystem to which this force should be added
body1	the first body to which the force should be applied
station1	the location on the first body at which the force should be applied
body2	the second body to which the force should be applied
station2	the location on the second body at which the force should be applied
force	the magnitude of the force to apply
