Q2) It has been observed that a workshop machine induces high vibration at an operating speed of 6000rpm. An absorber (tuned mass damper TMD) of mass m2 is attached to the machine. The magnitude of the exciting force F0 is 300N, and the amplitude of motion of the auxiliary mass X2 is to be limited to 3mm. The absorber is designed as 2=m2k2=m1k1 a) Determine the parameters of the vibration absorber ( k2 and m2 ). Use, Fo=m22X2 b) Find the stiffness of the machine mount k1. Given the machine weight =3000N. c) State why do we need to have the auxiliary system
