In the context of rope strength, what happens with sharper bends in the rope?

When a rope experiences sharper bends, it results in a decrease in strength, although the reduction might not be immediately significant. The curvature of the rope introduces additional stresses that can compromise its structural integrity. The fibers are forced to bend around a tighter radius, which causes them to be placed under tension in ways they were not designed to handle.

This phenomenon is rooted in material science, as the bend creates localized stress concentrations that can lead to fatigue or even breakage over time. The decrease in strength is often gradual rather than abrupt, which may be why this concept can sometimes be underestimated. Proper rigging practices encourage avoiding sharp bends whenever possible, as they can lead to long-term issues with rope performance and reliability, which is critical in rescue scenarios.
