P1. (Do not hand in – solution posted ) The mass-spring-dashpot below has mass m = 2 kg, stiffness k = 20000 N/m, and damping coefficient c = 40 Ns/m. Write the response of the system below excited by the periodic force given below, for which F 0 = 4 π N and T = π /25 seconds. Is there a resonance? Compare the amplitudes of the first three Fourier terms in the response solution. P2 (Hand in) The mass-spring-dashpot below has mass m = 4 kg, stiffness k = 10000 N/m, and damping

Unformatted text preview: coefficient c = 20 Ns/m. What are the three most dangerous resonances (values of ω )? The base excitation response can be written in terms of an absolute coordinate x and a relative coordinate z = x-y. Write and compare the first three Fourier amplitudes X i for the x coordinate and Z i for the z coordinate, for each of the three resonance cases....
