🔍 Key Concepts

• Bending radius and fatigue of wire rope when it passes over sheaves • Relationship between sheave diameter (D) and wire rope diameter (d) in good engineering practice • How too small a sheave affects the internal wires of the rope over time

💭 Think About

• Think about what happens to individual wires inside the rope when they are repeatedly bent over a small sheave versus a large sheave. • Which range would most likely minimize internal fatigue and wire breakage during frequent mooring operations? • For heavy-duty marine service, do industry practices usually lean toward smaller D/d ratios or more conservative (larger) D/d ratios?

✅ Before You Answer

• Compare each option’s implied D/d ratio and ask: would this be considered severe bending or gentle bending? • Consider that mooring winch wires see repeated load cycles—which option best protects the rope over its service life? • Mentally rule out any range that seems too small to avoid sharp bending for a multi‑strand steel wire rope.
