Rotation resistant wire rope tends to wear from which part?

Explanation:
Wear in rotation-resistant wire rope tends to begin on the inside because the core and the inner strands take the most of the bending and rubbing during operation. As the rope flexes around drums and sheaves, the inner portions are pressed and slide against the core and neighboring inner strands, concentrating friction and wear there. The outer strands are more shielded by the rope’s lay and by contact with the drum, so they don’t wear as quickly at first. So the inner portion shows wear first and most notably.
