🔍 Key Concepts

• Structure of wire rope (strand vs. wire vs. core) • Meaning of the two numbers in a wire rope designation like 6x19 • Difference between strands and wires in rope construction

💭 Think About

• In a 6x19 wire rope, think about what is being multiplied: what does the first number describe and what does the second number describe? • Visualize a wire rope cross-section: what repeated elements do you see around the outside, and what is bundled inside each of those elements? • Which part of the rope is referred to as the core, and is the core usually counted in this designation?

✅ Before You Answer

• Be clear on the definition of a strand versus a wire in rope construction. • Confirm whether the first number refers to whole outer bundles or individual filaments. • Verify that the second number usually refers to the wires per strand, not to the core.
