12. Scrubbing
Scrubbing refers to the displacement of wires and strands as a result of rubbing
around or against an object. This, in turn, causes wear and displacement of wires and
strands along one side of the rope. Corrective measures should be taken as soon as
this condition is observed.
13. Fatigue Failure
Wires that break with square ends and show little surface wear, have usually failed as
a result of fatigue. Such failures can occur on the crown of the strands, or in the
valleys between the strands where adjacent strand contact exists. In almost all cases,
these failures are related to bending stresses or vibration.
