🔍 Key Concepts

• Elasticity and stretch characteristics of nylon line under heavy load • How shock loading affects different types of line materials • Situations where too much stretch could be dangerous vs. helpful

💭 Think About

• For each choice, ask yourself: would having a line that stretches a LOT under load be an advantage or a hazard? • In which task could a sudden parting (snapping) of a highly elastic line cause the most serious danger to nearby personnel or equipment? • Which task typically requires a line that holds length and tension more steadily, with less elastic ‘rubber band’ effect?

✅ Before You Answer

• Identify which applications benefit from shock absorption (some stretch is good) and which need low stretch (more control, less recoil). • Think about where crew are likely to be closest to the line if it parts and whips back. • Consider how cyclic loading (load on/off, jerking) affects a highly elastic line in each listed use.
