Web5.4.7 Example Problems in Forced Vibrations. Example 1: A structure is idealized as a damped springmass system with stiffness 10 kN/m; mass 2Mg; and dashpot coefficient 2 kNs/m. It is subjected to a harmonic force … 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.
