QUESTION 12 Q8 (c) For the above question, flind the value of the damping constant, c in Nm Take m-130 kg, k " 53206.586 N/m and ζ-0.18819, QUESTION 13 Q8 (d) A motor vehicle and its simple mathematical model that can vibrate in the vertical direction while traveling over a rough road is shown in Figure (below). The vehicle can be idealized as the system. The road surface varies sinusoidally and can be described as o- Y sin o t. The vehicle has a mass of m kg. The suspension system has a spring constant of k N/m and a damping ratio of C-0.15 Take m-3725 kg.k-2400 kN/m and w . 36 rad's ζ-0.15. QUESTION 10 Q8 (a): system with a mass of m kg as shown in figure (below) and its damped free shock absorber for a car is to be designed. The system can be considered as simple SDOF An vibration response is shown beside that. The damped period of vibration is to be Td sec. x(0) (wg) in rad's QUESTION 11 os. 16094 38 ardC-024อารยา QUESTION 12 Q8 (c) For the above question, flind the value of the damping constant, c in Nm Take m-130 kg, k " 53206.586 N/m and ζ-0.18819, QUESTION 13 Q8 (d) A motor vehicle and its simple mathematical model that can vibrate in the vertical direction while traveling over a rough road is shown in Figure (below).
