Which term relates to wire rope material strength rather than wire rope arrangement?

The term that pertains specifically to wire rope material strength is "Mps," which stands for Minimum Breaking Load (MBL) or Material Strength. This term is used to denote the maximum load the wire rope can withstand before failing, reflecting the inherent strength of the materials used in its construction. It is a critical parameter in determining how much weight a wire rope can safely support under various conditions.

In contrast, the other terms relate more to the configuration and arrangement of the wire strands within the rope. For example, "preformed" refers to wire ropes that have been shaped before being used, which affects their handling but not their material strength. "IWRC" (Independent Wire Rope Core) indicates a specific construction method where the core is made of wires rather than fiber, impacting rope performance characteristics but not directly measuring material strength. Lastly, "lang lay" describes the way wires are laid around the core, which influences flexibility and fatigue resistance rather than the strength of the wire material itself. Therefore, Mps is distinct in that it directly addresses the strength characteristics of the wire material used in the rope.
