Q

A crack in the deck plating of a vessel may be temporarily prevented from increasing in length by __________.

🔍 Key Concepts

• crack propagation and how stresses concentrate at the ends of a crack • difference between sharp corners and rounded holes for distributing stress • why temporary crack‑stopping methods don’t try to carry load, but to relieve stress at the crack tip

💭 Think About

• Look at each option and ask: which method changes the shape at the very tip of the crack so the stress is spread out instead of focused? • Which choice is commonly used in metal structures (ships, aircraft, bridges) as a quick way to stop a crack from running farther before a permanent repair? • Which option might actually hide the crack or add more stress instead of controlling its growth?

✅ Before You Answer

• Identify which options add metal over the crack versus which options change the geometry at the crack ends. • Ask yourself which method is known as a standard temporary crack‑arrest technique in structural steel work. • Eliminate any choice that would likely concentrate stress at the ends of the crack instead of relieving it.
