Daring Young Engineers on the Flying Trapeze: Using Circus Arts to Teach DynamicsIn an effort to playfully approach the study of dynamics in a hands-on manner, the course“Dynamics with Circus Laboratory” was developed and taught. This course coveredtopics including rotating reference frames, and rigid body dynamics. Unique to thiscourse were laboratory sessions held at a local circus school, in which students were ableto use experimental methods to explore topics covered in the course. • German Wheel: For the first lab in this course, students explored reference frame transformations. Before attending the lab session they were asked to calculate the velocity and acceleration of a point on a non-slipping wheel as it rolls in a straight path. During the lab, students were taught how to perform a cartwheel in the German Wheel. They took video of the exercise, and then used the Kinematic Analysis program KAVideo to plot the position, velocity, and acceleration of points on their body as a function of time. This data was then compared to the theoretical model that they derived. As expected, there was a very strong correlation between actual and predicted results. • Flying Trapeze/ Low-Casting: This lab investigates whether or not a simple pendulum is a good model for the flying trapeze. Students also consider whether a double pendulum models the motion of a flying trapeze. Both sensor data and motion capture data were used to compare students’ performance on the flying trapeze and the low-casting trapeze (essentially a miniature flying trapeze) with their theoretical model. • Bungee Trapeze: Students were asked to derive the equation of motion for a person stepping off of a trapeze while wearing bungee cords. This complemented lectures on springs, damping, and oscillations. During the lab session, the students performed this feat while wearing accelerometers, and were then asked to compare their theoretical model with the actual data. Effects of damping and oscillation were covered. Student feedback for this course was quite positive. As will be discussed in the paper, experimental results for the above exercises were quite consistent with the theoretical models. In cases where there were significant differences between the experimental and theoretical results, the opportunity was used to discuss issues such as experimental error.
