Welcome to the Mechanical Engineering Case Studies website. Select your course from the list at the Left to begin.

This web site is being developed to give undergraduate Mechanical Engineering students real engineering examples and experimental data in their lecture courses. This is done by using design calculations or experimental data completed by ME seniors in their design courses, lab courses, honors thesis, and Co-op (with permission from the company). Results from graduate student research or published experimental data are also used. This allows students to become familiar with data analysis and the inherent uncertainties in experimental measurements before entering the laboratory courses.

The case studies are formatted as a homework assignment. In some cases, the entire case study would be assigned for homework. In other cases, there are several similar sets of data and only one set of data would be assigned for homework. Each case study includes a description of the objectives, the experimental facility, and the experimental procedure used to obtain the data. When possible, photos and video clips are used to show the facility and experimental procedure. From the web site, students can download engineering drawings of the models used in the experiment and spreadsheets containing the experimental data. The web site describes the data analysis required in the assignment. Included in the data analysis may be nondimensionalization, statistical analysis, plotting the experimental data, and comparison of the experimental results with correlations found in the text.

In this case study web site you will also find several ethics case studies and several links that have been found for particular classes. A statistics tutorial gives a review of the statistical analysis that is used in several case studies.

If you are interested in contributing additional case studies, or have any comments or suggestions regarding this site, please contact Professor Laura Pauley (lpauley@psu.edu).
