The spring constant of one car's spring is 24 kN / m and one tire has a mass of 370 kg. The relative damping factor is 0.35. The unevenness of the road causes a force on the wheel at a frequency of 0.74 Hz and the amplitude describing the unevenness of the road is 22 mm. What is the vibration amplitude of the car body in whole millimeters? For damping vibration

The spring constant of one car's spring is 24 kN / m and one tire has a mass of 370 kg. The relative damping factor is 0.35. The unevenness of the road causes a force on the wheel at a frequency of 0.74 Hz and the amplitude describing the unevenness of the road is 22 mm. What is the vibration amplitude of the car body in whole millimeters?

For damping vibration

1+4. D² - p2
T =
(1 – r2)2 +4 · D² - p²
