Updates To A Sequence Of Thermodynamics Experiments For Mechanical Engineering Technology Students, Roger A. Beardsley Jun 2013

Updates To A Sequence Of Thermodynamics Experiments For Mechanical Engineering Technology Students, Roger A. Beardsley

All Faculty Scholarship for the School of Graduate Studies and Research

This paper presents an outline of thermodynamics experiments and lab activities that accompany the introductory thermodynamics course for Mechanical Engineering Technology juniors at Central Washington University (CWU) in Ellensburg, Washington. It outlines and describes the current suite of thermodynamics lab activities, comparing the current suite of seven lab activities to a sequence outlined in an ASEE conference paper presented in 1995. Some lab activities in that paper have been replaced, while others have been updated. For example an experiment to measure the Joule-Thomson coefficient has been replaced with a First Law energy balance activity and the former First Law experiment …


Measuring The Impact Of Internships On Design Using A Materials Activity, Craig Johnson, Charles O. Pringle, Nathan Davis Jun 2013

Measuring The Impact Of Internships On Design Using A Materials Activity, Craig Johnson, Charles O. Pringle, Nathan Davis

Engineering Technologies, Safety, and Construction Faculty Scholarship

Our research question focused on how previous student experience, like a job internship, affects an ability to demonstrate engineering design skills. Principal student experience focused on prior industrial experience (e.g. internships), but also included annual project participation (e.g. ASME Design Challenge Teams). The scope of this effort included the creation and application of a design activity, resulting in documents that were evaluated with a metric. The activity focused on the effect of material selection and analysis with regard to ‘design performance’. Creating these activities, and using them to assess design skills is the novel aspect of this effort. Two classes …


Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman Jan 2013

Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman

All Master's Theses

The importance of cultural resource preservation cannot be overstated; however local economies are at least as important. Due to conservative archaeological site protection practices in Region 5 of the United States Forest Service, the economy of Northeastern California is being adversely affected. In an attempt to help the Forest Service make more informed management decisions and improve the Northeastern California economy, I undertook experiments on the effects of timber harvesting on lithic scatters on Modoc National Forest. The experiments involved placement of 225 glass tiles (proxy lithics) in each of three plots subject to vehicle traffic and log dragging by …
