Conversion Of Physics Based Labs To An Engineering Physics Curriculum

Abstract

In recent times there has been a shift of enrollment of undergraduates from more traditional, research-oriented physics curricula toward more general, applied, engineering physics curricula. As part of this process, the emphasis of activities in undergraduate laboratories must shift from a sole focus on understanding physical phenomena to include a focus on providing the tools and experiences that will allow graduates to apply experimental methods in the development of new processes and products. In a larger, research-oriented engineering university, this change in emphasis may simply result in collaborative efforts between the physics and engineering departments, and local industry. In a more isolated regional university the supporting engineering college structure often does not exist. This paper discusses the evolution of laboratory experiences in the Engineering Physics program at Murray State University (MSU) involving applications from both mechanical and electrical engineering.Refinement of the MSU Engineering Physics curriculum and subsequent ABET accreditation illuminated the students' need for applied mechanical and electrical laboratory experiences. In the original physics-based curricula, labs involving mechanical application were practically nonexistent. To provide for new mechanical lab activities, basic laboratory stations were procured, an engineering measurements lab and course were created, and innovative, low-cost practical experiences were developed. These activities quickly became too numerous for a single course, and will need to be distributed into the engineering science courses. The electrical engineering component has been influenced by technology advances and changes in focus. Improvements to laboratory equipment and software have simultaneously simplified many lab measurements while allowing for more complex projects. The focus has shifted from fundamental physics measurements (e.g., an electron's charge) to applied engineering measurements (e.g., a circuit's time constant), and to incorporation of a significant design component. This paper discusses the equipment, software, and design exercises for courses in analog circuits, digital circuits, and mechanical measurements taught within an Engineering Physics curriculum.
