🔍 Key Concepts

• Wire rope constructions and how fiber cores are used • Difference between lay types (lang lay vs regular lay vs spring lay) • How fiber can be combined with wire strands (center core vs mixed strands)

💭 Think About

• Ask yourself: which term specifically describes wire strands twisted around a fiber center core, combining metal and fiber in one rope? • Which options describe the direction or pattern of the twist rather than the materials that make up the rope? • Which choice is a general property of how the rope is manufactured, and which one directly points to a combination of wire and fiber?

✅ Before You Answer

• Identify which answer choice refers to materials (wire + fiber), not just twist direction • Eliminate any terms you know are about lay direction/strand pattern only • Recall from seamanship texts the definition of spring lay and how it differs from all‑wire or all‑fiber rope
