Described is a demonstration which uses two electrodes attached to a piezoelectric buzzer that operates when inserted into a lemon. The calculation of cell potentials and the effects demonstrated are discussed. (CW)

Describes a technique for using lecture-laboratory facilities and faculty office facilities to provide students a site for intensive laboratory exercises. Provides a layout of the lecture-laboratory facilities and energy systems of the facilities. Presents an instructional example on the concept of the natural frequency of single-degree-of-freedom…

Presented are the accreditation standards for engineering schools as developed by the Accreditation Board for Engineering and Technology (ABET). Discussed are various challenges presented by the standards and the need to improve engineering education. Items considered are developing a definition of a "good" engineering education, topics…

The concept of displacement center for teaching the virtual work method in statistics is described. An analytical treatment of the displacement center is presented. An example which illustrates the essential elements of this concept is provided. (CW)

The development and function of the pendulum clock is discussed from a historical perspective. Computations for the period of and forces acting on a pendulum are presented. The remarkable workmanship of early clock makers is described. (CW)

Presented is an experiment which provides a study both of the end correction involved with open pipes and also of the effect that varying the size of the tone hole in the pipe has on its fundamental frequency. Discussed are equipment, formulas, background, and methods. (CW)

Applications of this model to problems associated with basic phenomena in radioactivity, heat transfer, neutron chain reactions, RC circuits and vacuum pumping are presented. Example computations for each situation are included. (CW)
