Consider the single degree of freedom spring-mass system shown in Fig. P5.3, where k 4 x 10 N/m and m 8 kg. It is being excited by a harmonic forcing function, Fieoyt, at a frequency, @r. (a) If the excitation frequency is 200 rad/s, design a dynamic absorber to eliminate the vibration at coordinate x1. The only available spring for use in the absorber is identical to the one already used in the system. (b) If the 4x10 N/m absorber spring is used in conjunction with a 2 kg absorber mass, at what forced excitation frequency (in rad/s) will the steady-state vibration of coordinate x1 be eliminated? k m * to Consider the single degree of freedom spring-mass system shown in Fig. P5.3, where k 4 x 10 N/m and m 8 kg.
