Extracted text: Fundamentals of Vibrational Analysis Develop a sequence of at least three improved approximations for mathematical modeling of the following situations. b. The figure shows a human body and a restraint system at the time of an automobile collision. Suggest a simple mathematical model by considering the elasticity, mass, and damping of the seat, human body, and restraints for a vibration analysis of the system.
