Question: 1 / 400

What percentage of strength does a figure eight on a bight reduce rope strength by?

10 percent

20 percent

The figure eight on a bight is a commonly used knot in rescue operations and climbing, known for its simplicity and security. When tied in rope, it typically reduces the overall strength of the rope by approximately 20 percent. This reduction occurs due to the bending and pinching of the rope as it passes through the knot, which creates localized stress points that can weaken the fibers.

Understanding the impact of knots on rope strength is crucial for safety and effectiveness in rescue scenarios. The reduction in strength can influence decisions regarding the type and amount of rope used, especially in critical situations where maximum load-bearing capacity is essential. Maintaining awareness of how various knots affect rope integrity allows rescuers to make informed choices about their gear and techniques, ultimately enhancing operational efficacy.
