An excitation (Force) 60sin(ot)+80 cos(1) N produces a steady-state response (particular solution) whose quasi-static amplitude is 50 mm. The natural frequency of the system is 20 Hz, and a = 18 Hz produces a steady-state response that is in phase with a sine response. Determine the amplitude of the displacement (x) when ( = 18 Hz. Hint: The system is in damped vibration.

In damped motion, what decreases with time? Frequency Amplitude Wavelength Period The purpose of a shock absorber on a car is to prevent the car from bouncing when you go over a pot hole. Therefore a shock absorber should be: underdamped overdamped Resonance will occur when: the excitation frequency is near the natural frequency the damping is small both the excitation frequency is near the natural frequency and the damping is small
