Question

1. The plot in Fig.1 (a) shows amplitude response of the system illustrated in Fig.1 (b) a centrifuge as a function of frequency with a specimen, m2, in the machine. The mass of the centrifuge is m land it's restrained by a spring of stiffness k. Given that radius of the spinning chamber is 0.1 m and the mass m1 is 100 kg, find the mass of the specimen as well as the spring constant k.FEM
