In TPM, which is an example of a hidden failure?

• A. Cutter Vibrations
• B. Compressor burns out
• C. Loose Bolts
• D. Broken belt under the machine

Answer: (C)

Hidden failures are faults that exist in a machine but aren’t evident during normal operation or routine checks, until they interact with a loading condition or another issue and cause a breakdown. A loose bolt fits this idea well because it can loosen gradually due to vibration and heat without immediately signaling a problem. Operators may not notice it right away, and the system may still run, but the looseness can lead to misalignment, wear, or a sudden failure later on. The other scenarios show more obvious, detectable problems—a belt that’s broken is visibly broken, compressor burnout is a clear failure, and cutter vibrations are observable symptoms of an underlying issue.
