WebIn this case, the magnification factor is 1/(2ζ), and the phase angle is 270 degrees. The dynamic amplification factor and phase lead are shown in Figure 1-5 and are plotted as functions of forcing frequency. WebNow you know how to shift these things. Adding a phase constant will shift it to the left. Subtracting will shift it to the right. And the larger the phase constant, the more it's shifted. You don't ever really need to shift it by more than two pi since after you shift by two pi, you just get the same shape back again.
