Perhaps the simplest illustration of a mechanical vibration is a vertical spring with weight, as shown in Figure 1. In this position, the deflection of the spring from its free state is just sufficient to counterbalance the weight W. This deflection is called the static deflection of the spring. The position in which the spring is at rest is #1. The spring is then slowly extended to position ...
