🔍 Key Concepts

• Wire rope construction notation (what each number group means) • Difference between strands, wires, and diameter in wire rope • How wire rope size is normally specified in the maritime industry

💭 Think About

• Think about what part of the rope the first number (6) is likely to describe: is it individual wires, groups of wires, or something else? • Consider what the second number (24) usually counts in a wire rope construction: are we usually counting strands again, or smaller elements within the strands? • Ask yourself how 1-3/4 inch is normally used when ordering or describing wire rope on a vessel: are you talking about thickness, length, or something like circumference?

✅ Before You Answer

• Be clear on the difference between strand vs wire in a wire rope: which is the larger unit? • Remember that wire rope size in inches in deck operations is typically given as diameter, not circumference. • Eliminate any option that mixes terms not normally used in wire rope description (for example, yarns are more common in fiber line than wire rope).
