How are leaf springs categorized?

Leaf springs are primarily categorized based on their configuration and construction characteristics. The correct classification includes options that denote whether they are of a single-point attachment or have multiple points of support and connection.

In the case of single-point and dual-point classifications, leaf springs can be designed to attach to a vehicle's frame at either one or two points. This distinction is important for understanding the suspension dynamics, as a single-point leaf spring allows for more articulation when compared to dual-point designs that may offer increased stability and load support due to their two attachment points. These configurations will affect how the spring behaves under load, such as in terms of articulation, flexibility, and damping characteristics.

Other options that reference terms such as tri-point or various rate categories do not hold the same relevance in typical leaf spring classifications. Therefore, focusing on single-point and dual-point reflects the primary characteristics that directly influence the suspension system's performance in vehicles.
