The main purpose of the safety wire, as suggested by Team 1678, was to prevent our fairlane flywheel from expanding a significant amount past 5000 rpm. During prototyping, the fairlane wheels expanded to the extent that we were fearful of testing them out. As a result, the safety wire constrained the expansion of the wheels to a certain diameter which allowed us to ramp up to around 6000 rpm at Champs for taking shots. As for the process of installing them, the safety wire was wrapped once around the wheel, cut to its length, and then two ends were twisted together and then stuck inside the neoprene so as to prevent it from contacting the boulder. I have attached a picture of the flywheel below.
