Question 1 of 2066636ee728f7522a1c5176f6

Close link chain of not less the 3/4" (or the wire rope equivalent) is required for lashing deck cargoes of timber. What size flexible wire rope would provide the strength equivalent to 3/4" chain, using a safety factor of 5?

🔍 Key Concepts

• Breaking strength vs. safe working load (SWL) and how a safety factor of 5 affects the required strength • Relationship between chain size, wire rope diameter, and their relative strengths • Typical comparative strength of flexible wire rope vs. close‑link chain of the same nominal size

💭 Think About

• First, think about what the safety factor of 5 means in terms of the minimum required breaking strength of the chain and of the wire rope. • Compare how strong flexible wire rope usually is compared to chain: is wire rope generally stronger, weaker, or about the same as chain of the same diameter? • If wire rope is stronger than chain for the same diameter, should the equivalent wire size be smaller, equal, or larger than 3/4" chain to give the same safe working load with the same safety factor?

✅ Before You Answer

• Be clear whether you are comparing breaking strength or safe working load; don’t mix the two. • Consider that flexible wire rope (like 6×19 or 6×37 construction) typically has a higher breaking strength than chain of the same diameter. • Before choosing, ask: “Does this diameter make sense if wire rope is usually stronger than chain?” and eliminate obviously too large or obviously too small sizes.
