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.

##L3P3 About Vehicle Dynamics In general, vehicles have a steering system whose design approximates 55% to 70% of the Ackermann geometry. Is it possible to have a steering mechanism that exceeds 100% of the Ackermann geometry? If so, make a diagram of this mechanism. Considering that there are different types of steering mechanisms, construct the geometric diagram of five examples applied to vehicle dynamics.
