Consider the quarter-car with mS = 300 kg, mU = 40 kg, kS = 15 N/mm, kt = 160 N/mm. Calculate the frequencies associated with the two simplified models (ride, wheel hop) and compare with the actual frequencies of the two-degrees-of-freedom model. Calculate the modal vectors and comment on the ride isolation. Calculate the static deflections
