HW An clectric motor is mounted on a steel table. The deflection of the table under the weight of the motor is observed to be 4 mm. the mass of the motor added to the effective mass of the table is 50 kg. The rotating parts of the motor have a mass of 10 kg and have an eccentricity of 12 mm. During free vibration, it is observed that the displacement of 40 mm is reduced to 2 mm in 1 second. Find the amplitude of motion if the operating speed of the motor is 1750 rpm. Assume the damping is viscous.

2- I need answer of all sub-parts questions. Thanks 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 resultant frequency ratio of the above model. Calculate the steady state amplitude of the vehicle. Determine the force amplitude that will be felt in the vehicle at the steady-state due to the bumpiness of the road.
