Use modal analysis to calculate the response of the drive train system of Problem 4.44  given by the matricies to a unit impulse on the car body (i.e., at location x3). Use the modal damping of  10% in each mode. Calculate the solution in terms of physical coordinates, and after   subtracting the rigid-body modes, compare the responses of each part

Free Damped Vibrations

Free vibration is a type of vibration in which the external force is removed after giving the initial displacement to a body/system. In other words, in this type of vibration, force is applied at the initial displacement of the system, and after the initial displacement, force is removed, and the system vibrates at the natural frequency.
