Vibrations Question

The governing equation of motion for a base motion system is given by (assume the units are Newton)

mx''(t)+ cx'(t)+kx(t)=cYwbCos(wb*t)+kYSin(wb*t)
Given that m = 180 kg, c = 30 kg/s, Y = 0.02 m, and
wb= 3.5 rad/s
Find the largest value of the stiffness, k that makes the transmissibility ratio less than 0.85
