🔍 Key Concepts

• Anchor cable geometry and load paths between anchor, anchor ring, connecting shackle, swivel, and first cable links • How twisting and rotation of the cable affect stress on end links and the anchor ring • Purpose and correct use of swivels and shackles in anchor systems

💭 Think About

• Which option most directly reduces bending and twisting forces on the end links and anchor ring, rather than just protecting or covering them? • Think about what happens to the chain when the vessel swings at anchor—what part must be able to move freely to avoid transferring twist into the end links? • Which choice would actually increase stress concentration by reducing size or restricting movement?

✅ Before You Answer

• Identify which component in the system is designed to rotate and relieve twisting loads in the cable • Eliminate any option that would concentrate stress (smaller parts or rigid add‑ons) rather than distribute it • Ask whether the option affects movement and alignment of the chain with the anchor under varying directions of pull
