🔍 Key Concepts

• Relationship between number of wires per strand and properties of wire rope (flexibility vs durability) • How cargo runners are used (bending over sheaves and contact with cargo gear)** • Difference between flexibility and abrasion resistance in wire rope design

💭 Think About

• Think about what changes when you go from a 6x19 construction to a 6x37 construction in terms of wire size and surface area. • Ask yourself: does more, smaller wires make the rope tougher against surface wear, or more flexible but easier to damage on the outside? • Consider what cargo runners experience in service: are they more affected by tight bending, surface wear, crushing on the drum, or overall length?

✅ Before You Answer

• Compare the wire diameter in 6x19 vs 6x37 and what that means for surface wear. • Decide which property is more critical for a cargo runner: flexibility or resistance to external wear/abrasion. • Verify that options like "longer" or "less expensive" are not inherent properties of a wire rope construction (6x19 vs 6x37).
