Answer the following:
1) The system is subjected to a force F = p0 sin(ωt) where p0 isequal to 106 and ω is equal to 60 rad/s. Once its steady statecondition is reached, the system response exhibits a delay withrespect to the load which corresponds to an interval of tr = 0.0087s. What is the value of the damping ratio, ξ?
2) What is the amplitude of the displacement at steadystate?
3) What is the value of the dynamic amplification factor insteady state?
4) What would be the phase angle and delay of the system tr ifthe damping ratio of the system had a value of 21.26%?
