Question 26

The amplitude and frequency of vibration as well as the _________ of the components are critical factors in vibration-induced fatigue.

    Correct Answer: D

    The amplitude and frequency of vibration, as well as the material properties of the components, are critical factors in vibration-induced fatigue. Material properties, such as strength, hardness, and microstructure, directly influence how a material responds to cyclic stresses and strains, making it a key factor in determining the fatigue life of a component.

Discussion
ahmadmmOption: D

Geometry, stress level, number of cycles, and material properties (strength, hardness, microstructure) are predominant factors in determining the fatigue resistance of a component. The amplitude and frequency of vibrations (related to stress level and number of cycles) in vibrating equipment such as piping are also critical factors.
