Although a previous study of a sophomore-level engineering mechanics(statics and dynamics) course found that exam wrappers did not have a significant
their interpretations and defi-nitions. We propose collecting these and presenting them at ASEE 2019. 2 The authors acknowledge that the exercise is challenging and requires some mathematical rigor. A formerMSOE undergraduate mechanical engineering student, Elise Strobach, who is currently pursuing doctoral studies atMIT, successfully solved for the limits. Most students do not take on the challenge.Conclusions The paper explores limiting behavior of lumped-parameter, second-order systems and showshow expressions for second-order parameters reduce to first-order time constants in the limits.Expressions for a natural frequency appear to exist for any second-order system, whether or notthere are two types of energy storage elements for

However, such tools have been seldom used in science,technology, engineering, and mathematics (STEM) education, mostly because of the technicalnature of the subjects. The objective of this study is to investigate the features of audio studymaterials that could improve student learning and

real-time feedback onhand-drawn free body diagrams for students. The system is driven by novel sketch recognitionalgorithms developed for recognizing and comparing trusses, general shapes, and arrows indiagrams. We have discovered students perform as well as paper homework or other onlinehomework systems which only check the final answer through deployment to five universities with450 students completing homework on the system over the 2018 and 2019 school years. Mechanixhas reduced the amount of manual grading required for instructors in those courses while ensuringstudents can correctly draw the free body diagram.
