Question

Because of unbalance, A harmonic force of maximum value of 20, 000 N and frequency of 1800 cycles/min acts on a machine of 450 kg mass. Design a support system for the machine (i.e., choose k) so that only 4000 N force is transmitted to the base supporting the machine.Assume a damping ratio of 0.05.a. the transmissibility,b. the value of k.c. the amplitude of the displacement due to the unbalance force.
