Question 1 of 27070

Q

Extended cyclical variations in tensions will cause an anchor chain to break due to __________.

🔍 Key Concepts

• Mechanical properties of metal under repeated loading • Difference between gradual weakening vs. surface wear vs. chemical attack • How anchor chains actually fail after long periods of cyclic loading

💭 Think About

• Ask yourself: what do we call the process where metal is weakened and eventually cracks after many cycles of loading and unloading, even if the load is below the breaking strength? • Which choice describes damage caused by repetitive stress inside the metal, rather than outside surface wear or rusting? • Think about how a chain on an anchor in a seaway is constantly being pulled and relaxed—what long‑term effect does that have on the metal’s internal structure?

✅ Before You Answer

• Distinguish internal cracking from repeated stress vs. external surface wear • Separate chemical processes (like rusting) from mechanical processes • Think which option is most directly tied to cyclic loading over time, not a one‑time overload or simple deformation
