The spring is a fully adjustable spring for BeamNG. This means size, stiffness, damping, strength, etc, can all be modified in game. Allowing players to set up the spring exactly to their own needs.
This spring was used to create a wiki article that explains the basic theory behind the BeamNG physics engine. For new modders to the game, this article is intended to be the first they read, to provide a solid foundation of knowledge for which to build their own mods upon.
