Which consequence results when dry flax rope anchoring a Viking 'byrding' cargo ship's sail experiences abrasion against a rough-hewn wooden mast?

💡 Explanation

Rope abrasion causes fiber degradation, reducing yarn count through a fretting mechanism, because the localized stresses on abraded fibers concentrates loading; therefore, the ropes weaken, rather than make the system more elastic, because increased fiber yield would occur instead.
