WebForced vibrations. Vibrations of a body under the constant influence of an external periodic force acting on it are called the forced vibrations. The external applied force is called the … WebApr 24, 2024 · The impulse I is then I = F ⋅ Δ t, where F is the force (assumed constant) and Δ t is the time duration that the force acts. So, on first glance, you could say that the equation of motion is: x ¨ + 2 ζ ω n x ˙ + ω n 2 x = F ( t) m e q. However, if you think about it after the force stops acting, then essentially you have a free vibration.
