Q

What is a normal safe working load for used nylon rope in good condition?

🔍 Key Concepts

• Safe working load (SWL) vs. breaking strength – how they are related • Safety factors commonly used for synthetic fiber lines like nylon • How elastic/stretchy behavior of nylon affects the safety factor compared with wire or manila lines

💭 Think About

• First, think about whether it is ever considered safe to work a line close to its breaking strength, even if it is in good condition. • Consider which material (nylon vs. manila vs. wire) is usually given the largest safety factor, and why that might be. • Ask yourself: for a dynamic, shock‑absorbing line like nylon, should the working load be a small fraction or a large fraction of the breaking strain to stay safe under surges and snatches?

✅ Before You Answer

• Make sure you are thinking in terms of a fraction of breaking strength, not the other way around. • Recall that standard practice uses a large safety margin (safety factor) for nylon due to its stretch and possible shock loading. • Eliminate any choice that would regularly put the line under high percentage of its breaking strain during normal operations.
