Which statement about shock loading is true?

• A. It should be avoided by stopping gradually
• B. It should be ignored for light loads
• C. It should be tested with a hand-over-hand method
• D. It should be removed from service

Answer: (D)

Shock loading is a sudden, transient high load that can exceed what equipment was designed to handle and cause immediate damage or hidden fatigue. When this happens, the safest and most prudent action is to remove the equipment from service and inspect for damage before reusing it. This approach prevents a potential failure in operation and ensures any cracks, deformations, or loosened connections are found and repaired.

The other options don’t fit because stopping gradually doesn’t guarantee safety after a sudden overload, ignoring it for light loads is dangerous, and testing with a hand-over-hand method isn’t an appropriate or safe diagnostic in this context.
