Separate names with a comma.
High I was hoping that if anybody has a value for their Cda and if they would like to share it along with tire model(to reference crr). I have...
[IMG] Weighing in at a staggering 4.5 pounds(due to my own theories on wheel inertia) here is a up close and personal shot on my custom...
got me again.
Making the approximation for steady velocity riding that the water column will began to flow in unison over time yes it would be a straight...
Yeah its tough stuff but its still interesting.
what if you were riding on the moon? and you did not have to deal with aerodynamics?
I speak to my professors regularly about this. I've taken many lab courses and know how difficult it is to control a experiment and get worthwhile...
work done by gravity does not include frictional losses. Really we're just talking semantics at this point.
If you road a steady velocity because of friction the water would eventually approach the same rotational speed of the bike wheel. Accelerating...
the trials weren't done days apart. They were done about 15min apart.
The point is that by finishing where you started you eliminate the variable of work done on or by the gravitational field making the test a more...
Yeah I realize all of that. The point is that because gravity is a conservative field if you finish where you start you've done no work in the...
Yeah but beer inflation would be a great excuse to have a party.
All true, but all the gravitational potential you loaded yourself up with will be returned to you on the descent to help you overcome these...
Yeah I've seen this. What would be interesting is to see this test where they turned around and came back down to finish where they started....
I was thinking if I do the test in the future it will just test whether which is faster water or air. Not necessarily about higher or lower...
Cool you know your most likely right about everything and I'm just jumping to conclusions. Wish I wasn't injured so I could continue to test...
All true but testing this in field is very difficult to control all the variables and obtain equipment that doesn't change any of them. I'm well...
Even if you cancel out the moment of inertia vectors, the wheels will still each individually resist moving out of their plane of motion although...
cool thanks for the insight. Do you have controlled infield data about wheel inertia by chance?
