I recently found an older academic paper that was published from the Uni of Illinois from 1989 reporting on an ‘innovative approach’ to teaching mechanical engineering undergrad students System Dynamics. It involved the students investigating open-ended engineering design questions in relation to bicycles for a full semester. I love how in the introduction section pointedly justifies that ‘the bicycle is not a trivial topic, as one might suppose at first glance, but it is a rather formidable subject of study’ (Klein, 1989, p 4).
Bicycles challenging engineering ‘truths’
The paper goes into detail about the learning, philosophical and pedagogical principles for using bicycles as the instruction tool and how the program, class and resources were managed and major beneficial outcomes from the program.
The students applied a number of the theoretical concepts they were learning in class to the bicycles, thus modifying bicycles to take into account engineering qualities such as ‘zero-gyroscopic’ bicycles, which are ridable and therefore refute a common held scientific misconception that it is the gyroscopic effect of a bicycles rotating wheels that keep the bicycle upright -mythbusted!
Engineering modifications
The students put the bicycles through a number of different hardware modifications (such as flyball governors, raw egg dynamics, hydraulic servomechanisms and Passive R-L-C circuits) and apply various calculations and manoeuvrer to the bikes to test an array of laws, theories and modelling dynamics. One of the most successful modifications the students applied was a rear-seated bicycles. Overall, many of the augmentations to the hardware that the students applied were evaluating outcomes of how power, stability, dynamics and functionality to see how they were effected.
So can they now answer..
Also, the engineering students were required throughout the semester to write their findings up in essays, of which included topics like:
