a scanning electron microscope (SEM). There are several points ofcontention that make fatigue testing difficult while being observed by an SEM: (i) Building afatigue testing machine small enough to fit within the SEM chamber is a different task; (ii)Building a fatigue tester small enough to fit within the SEM is feasible but most of the onescreated for market use are costly; (iii) Building a fatigue tester that can still apply the loadscorrectly to the sample and at the correct frequency is a difficult task; and (iv) A system thatapplies cyclic loads to a sample will create vibrations and will obscure the SEM from correctlyobserving the sample. The goal of this capstone project was to design a micro-fatigue tester forin-situ monitoring of

-Based-Learning (PBL) for skillsdevelopment, motivation, and retention (both in terms of students staying in the major and interms of retaining learned skills) of engineering students. While all students take design coursesleading to their senior capstone projects, they do not all build prototypes of their work. Typically,in naval architecture and marine engineering programs, PBL projects focus on building smallmodels due to time, space, and cost issues with using full-scale vessels. Exceptions to thisapproach are taken at two colleges, where students may take elective courses that feature full-scale construction of 10-15 ft long plywood craft. At the United States Coast Guard Academy(USCGA), the first-year, 1-credit, course introduces
