70% to passWhen measuring vibration, an engineer should be concerned with recording the velocity or displacement of the measurement. Which other factor should also be of concern?
AkW
BFrequency
CAmplitude
DAmps
AI Explanation
The correct answer is B) Frequency. When measuring vibration, the engineer should be concerned with recording the velocity or displacement of the measurement, as well as the frequency of the vibration. Frequency is a critical factor because it can indicate the source and potential impact of the vibration. High-frequency vibrations may be indicative of bearing issues, while low-frequency vibrations could signal problems with equipment alignment or imbalance. The other options, such as kW (power), amplitude, and amps, are not directly relevant to the specific factors of concern when measuring vibration.
