Useless Information: Crack Nucleation

The article itself provides little real world information other than theoretical descriptions of how crack nucleation begins to appear in metals. It was free though. However, it is always useful to think about all the repeated expansions and contractions of hubs, the oscillations, the loading and un...

Re: Definitive Tests on the Heating and Cooling of Hub Motor

Love the work! I settled on bolt on. No cover modification, just sandwiched between what comes factory. No direct contact between the fluid and the windings, but far easier/less mess, and impressive results. I still used transmission fluid though, now whether this was a real gain (especially conside...

Re: 'Theft of power' lands electric-car driver in jail

I was speaking in jest, but my point is this: Respect is given. Small amounts of electricity are given as a token of respect. We need more of these informal relationships built on respect. As soon as we begin claiming things as a right, it needs objectively evaluated. This is the royal road away fro...

Re: Rolling Resistance (RR) - Understanding Tires

Nice find on the tires. I would love to hear how they work out, although my trike has 26 and 20" tires. Speaking of trikes, I am guessing you could ballpark rolling resistence for a trike by evenly dividing the space under the rr line, bisecting the angle and adding to the top? Sound reasonable? Onl...

Re: Rolling Resistance (RR) - Understanding Tires

So, if that first graph is in kph, that would mean air resistence overtakes rolling resistence around 18kph or a paltry ~ 11 1/2 mph?
