Forced vibration of particles

Published by dun d on

For the system shown below, m1 = 664 g, m2 = 93 g, c = 112 Ns/m, and k = 75.63 N/mm. The system is being driven periodically by an external force F with 3,192 N amplitude at 87 Hz. Assume lightweight pulleys, and that the cable remains in tension the whole time.

Calculate the magnitude of steady-state vibration amplitude of mass 1 in millimetres rounded to one decimal place.

answer is 26.4, no matter what i do i keep getting 47 where am i going wrong
