An introductory course in vibration engineering naturally begins with the basic "building block" concepts on which a deeper understanding is built. The study of single degree of freedom lumped parameter systems lays the conceptual groundwork needed for studying the behavior of multidegree of freedom or continuous systems. The simplest single degree of freedom vibratory system is of course the pendulum. Pendulum problems illustrate basic vibration theory very nicely, providing a simple and

Constructing these simple pendulum arrangements in a "testbed" environment and measuring the actual natural frequency provides a useful vehicle for extending theory into actual practice. This paper examines one particular pendulum problem and its implementation and use in a laboratory setting.
