Which of the following is a defect that would condemn a flexible steel wire rope from safe use?

A flexible steel wire rope exhibits various characteristics that determine its safety and functionality. Core collapse is a critical defect that compromises the integrity and strength of the rope. When the core—the internal part of the wire rope—collapses, it can no longer provide the necessary support or maintain the correct shape and functionality of the rope. This situation could lead to unexpected failures during operation, creating a significant safety risk.

Other conditions, such as the absence of color coding, minor surface rust, or normal wear, do not directly indicate a loss of structural integrity. These factors may require monitoring or maintenance but do not necessarily necessitate immediate condemnation of the rope. Core collapse, however, fundamentally alters the performance and safety of the flexible steel wire rope, warranting its removal from service.
