🔍 Key Concepts

• Anchor chain construction (link, crown, stud) • How a stud changes the shape and movement of a chain link • Common failure or problem modes of chain: kinking, twisting, spreading, breaking

💭 Think About

• Think about what happens to an open chain link under heavy load without anything across its middle. How can the shape of the link change? • Which problem would most likely be stopped by having a solid bar (stud) across the inside of each link? • Which of the answer choices describes a deformation of the link’s shape rather than a complete failure of the metal?

✅ Before You Answer

• Be clear on what a stud-link chain looks like versus an open-link chain. • Ask yourself which option is about change of link shape under strain, not total failure. • Eliminate any choice that describes something the stud is unlikely to physically stop once the metal has already failed.
