Given ωn= 20 rad/s and δst = 0.05 m, the frequency response function of the vibration system is given.
If the excitation function is
a. F(t) = 200 cos(10t) N,
b. F(t) = 200 cos(20t) N,
Using the figures above to obtain the steady-state responses of the system.
(Note: Phase angles use "radians", instead of "degrees".)
