failure under variable amplitude stress cycles is assessed using Miner’s rule. A: fatigue B: break C: compressive D: bending

When a phase winding of a resolver carries alternating current, the amplitude of magnetic density at each point in the air-gap is produced by the winding changes in ______ distribution at certain instant.

Two light sources are said to be coherent if they ( ) A: are of the same frequency. B: are of the same frequency and amplitude. C: are of the same amplitude, and maintain a constant phase difference. D: are of the same frequency, and maintain a constant phase difference.

很多控制器的输出都有可能产生振铃现象。振铃幅度RA (Ringing Amplitude) 可用来衡量振铃强烈的程度，与采样周期有很大的关系。

The average stress σm and stress amplitude σa of the alternating stress in the figure are respectively ( ).[img=239x154]17de8405f43ce66.jpg[/img] A: σm = 40MPa，σa = -120 MPa B: σm = -40MPa，σa = -40 MPa C: σm = 0MPa，σa = 120 MPa D: σm = -40MPa，σa = 80 MPa
