The figure shows a simple model of a motor vehicle that can vibrate in the vertical direction while traveling over a rough road. The road surface varies sinusoidally with an amplitude of 0.01 m and a wavelength of 6 m.

The vehicle has a mass of 1007 kg. The suspension system has a total spring constant of 40 kN/m and a damping coefficient of 20 kN.s/m. The vehicle average speed is v = 100 km/hr.

The objective is to determine the vehicle steady-state displacement amplitude as well as the respective transmitted force.

Calculate the forcing frequency of the pumpy road.
Calculate the natural frequency of the vehicle SDOF system.
Calculate the damping ratio of the vehicle SDOF.
