Jumping From Criterium Corner
Our standard rider is on 32 spoke standard wheels. Our
test rider is riding Specialized tri-spokes. Both riders jumped from a criterium
corner with the same initial speed. The riders are the same in all other
respects. For the same power output, which one will be ahead at the end
of 100 meters? By how much?
The motion equations say that the rider on the Specialized
wheels will be ahead by 18 cm after 100 meters, or about 0.015 seconds even
though the Specialized wheels are heavier by 49 gm and have higher rotational
inertia.
