What is a common symptom of misalignment during machine operation?

• A. Reduced power output
• B. Increased vibration and noise
• C. Lower energy consumption
• D. Improved efficiency

Answer: (B)

Increased vibration and noise is a common symptom of misalignment during machine operation because when components are not properly aligned, they can create irregular contact points that lead to excessive movement and friction. This abnormal behavior generates vibrations that can resonate throughout the machine and potentially into the surrounding structure. Additionally, as parts rub against each other improperly due to misalignment, they can also produce audible noise that can be an indicator of operational issues. Monitoring these vibrations and noise levels can help maintenance teams identify alignment problems early before they escalate into more significant failures.

Reduced power output, lower energy consumption, and improved efficiency generally suggest that a machine is operating well. However, when misalignment occurs, energy losses due to friction and wear typically lead to increased energy consumption and potentially reduced power output, making these options less relevant in the context of identifying misalignment symptoms.
