Greene, Nathaniel R.; Brunskill, Jeffrey C. – Physics Education, 2017
A two-axis solar tracker and its interactive kiosk were designed by an interdisciplinary team of students and faculty. The objective was to develop a publicly accessible kiosk that would facilitate the study of energy usage and production on campus. Tracking is accomplished by an open-loop algorithm, microcontroller, and ham radio rotator. Solar…

Rushton, Erik; Ryan, Emily; Swift, Charles – 2001
In this activity, students reinforce an antenna tower made from foam insulation so that it can withstand a 480 N-cm bending moment (torque) and a 280 N-cm twisting moment (torque) with minimal deflection. One class period is used to discuss the problem, run the initial bending and torsion tests, and graph the results. The second class is used for…
