Which of the following is an example of production floor failure?

• A. Worn-out bearings
• B. Power supply failure
• C. Brake failure
• D. Engine problems

Answer: (A)

On the production floor, failures are issues that stop or degrade the operation of the equipment that actually makes product. Worn-out bearings fit this idea because bearings support rotating parts; as they wear, they lose proper alignment, create excess play, generate heat and vibration, and can cause a machine to seize or trip. That directly leads to downtime, quality problems, and the need for maintenance—precisely what a production-floor failure is.

In contrast, a power supply failure is an electrical issue that cuts power to systems rather than a mechanical fault on a machine, and brake or engine problems are not typical wear-related failures on normal production equipment. So worn-out bearings are the clearest example of a production-floor failure.
