Total Score: 82.98
Range: 211.5 303.6mm
Weight: 1060.3 grams
Strength: 7.42 kN
Failure Mode: Axle sheared between two of the lobes
Video: Link
Comments: The webcam suffered from a few problems, the most notable being that the spring tension was insufficient to expand the lobes outward. One of the lobes also had its axle hole drilled a bit cockeyed, so it had a tenancy to miss the cam stop on the opposing lobe and invert. The big issue though was that the axle turned out to be rather weak and sheared surprisingly early. It was quite the sudden failure, with the cam being there one moment and on the floor the next. The slow motion of the video is quite amusing, so be sure to take a look.
