Measuring Strain in Trusses

Strain is an important quantity in engineering and materials science that relates the deformation of a material to its original length as a percent. Different materials exhibit particular qualities under loading, for example the amount of strain due to a certain magnitude of force, or the amount of strain that can be borne before failure. This experiment aims to compare the relative strengths of three common truss configurations by measuring the strain in their members under loading

Army-Navy Game: Sport as a Training for War

What insights can different disciplines and modes of inquiry offer about the legacies of war? How might integration of these insights help us learn more about the impact of war, broadly conceived? And what lessons might be drawn for the future? This presentation on how sport can be used as a peacemaking tool is part of Legacies of War and the Liberal Arts: Learning from Difference, a series of short, student-led talks that bring a variety of disciplinary perspectives — sciences, arts, humanities, and social sciences — to bear on arguably the most consequential experiences of human history. Patrick Cottrell, Associate Professor of Political Science at Linfield College, introduces the series of talks at the beginning of the presentation
