3.2.9 construction, n-geometric design description of the wire rope’s cross section. 3.2.8 classification, n-group or family designation based on wire rope constructions with common strengths and weights listed under the broad designation. 3.2.7 center, n-the axial member of a strand about which the wires are laid. ![]() 3.2.6 cable, n-a term loosely applied to wire rope, wire strand, and electrical conductors. 3.2.5.1 Discussion-The term breaking force is synonymous with actual strength. 3.2.5 breaking force, n-the maximum load at which a tensile failure occurs in the sample of wire rope being tested. 3.2.4 area, metallic, n-sum of the cross-sectional areas of all wires either in a wire rope or in a strand. This strength does not give recognition to the reduction in strength resulting from the angularity of the elements in the rope, or other factors that may affect efficiency. 3.2.3 aggregate strength, n-the strength derived by totaling the individual breaking strengths of the elements of the strand or rope. 3.2.2 aggregate area, n-see area, metallic. ![]() In addition, the following definitions for wire rope will apply: 3.2 Definitions: 3.2.1 abrasion, n-frictional surface wear on the wires of a wire rope.
