Axle weight?

I love these old videos. What we learn is heavy is better if it is located near the center of rotation.

So, fill our drilled axles with lead? :-)

If they are rolling down hill not under power the filled axle wins every time. Not lets put them on a flat surface and powered by a motor. I'll take the light weight ones every time.

Any reduction in overall weight would require less force to accelerate the car. The axle ,even though it’s spinning is still accelerated at the same rate as the rest of the vehicle. Is it possible that is why there is little to no ET reduction from a lightened axle or wheel ?

I was wondering how parts rolling down that board related to an engine having to accelerate that part. Small diameter & heavy will win that deal.

I was thinking the same thing.

I know it's a stretch.....it's covered in the third video, if your brain doesn't melt first. The acceleration of mass is.....the acceleration of mass.

Try building engines with a 50 lb crank rule.
