New website app that tells you how fast you can ride for a given turn on the street

Hey everyone.

Yesterday I had an idea. To create a tool that will allow you to input your favorite road on google maps and it will tell you how fast you can go around each bend for a given lean angle.

www.howfastcanigo.com

Hope you guys enjoys it!!! I made it for everyone I know, friends, and peers at the forums.

I'd take that down immediately if I were you. There are some serious liability concerns if someone uses that tool, then crashes at or under the speed your app says they can go, especially if it's under the speed limit (like a hairpin corner).

That said, it's a very cool application.

yeah.. see that highside thread in this section for proof of that. that is IMPOSSIBLE.

"oh i can take this 45mph corner at 90!! YAY!!!"


*hits gravel or sand or fresh pavement from earlier that day, or a deer*

"fuck i'm dead"

had you been actually acting right on the street, ya wouldn't be dead.
go to the fucking track.


i mean, its a cool concept and all, but DAMN you GOTTA know you're gonna get some retard riding FAR above his skill level just because the site said he could.

what would be cooler is if you could factor in variables that cause you to lose traction, like gravel, rain, cooler temps (so tires aren't warmed up) and then figure out, with the given road conditions how fast you could go.

but yeah, it's a liability and there will always be a squid up for the challenge.

It also doesn't account for "staying in your lane". In order to stay in my lane in a certain curve, there is NO way I could go the speed it states at the angle I chose.

Now, if I was using both lanes... then sure.

As it doesn't seem to take any account of camber, surface condition, entry and exit restrictions or sight lines for the street, it's worse than useless and will probably kill somebody. It also seems to have no input for model of bike/weight of rider, as both mass and placement of mass have an effect on the relationship between lean angle and speed. This loooks like some half assed schoolboy app.

I hope you have a good lawyer.

All this is just ADVICE because at the end of the day, you can do whatever the FUCK you wanna do.

Thank for your comment.
Any single track vehicle, motorcycle, bicycle etc will have the exact same lean angle per given radius and speed.

This concept is difficult for most to understand.
Lean angle is "the angle at which the force of gravity which is trying to pull you down is exactly offset by the centrifugal force being generated."

Represented by: lean angle = arctan(v^2/g*r)
v = velocity in m/s
g = 9.81 m/s^2
r = radius in meters

So, no. Mass of rider + bike, wheelbase, C.G. height has no effect on the relationship between radius, speed, and lean angle.

The easiest way I can explain this is the following:
When you travel in an airplane and the airplane turns, your cup of water is not spilling over. The water is perfectly level in the glass even though the plane is banking.

Now imagine a Cessna 172 flying at 140mph banking at 30 degrees
Now imagine a Boeing 747 flying at 140mph banking at 30 degrees

Will both fly the same radius arc? If you answered yes - you are right.

A Harley, a bicycle, and an Ninja zx6r are all going into a 200 foot radius turn at 50mph.
THEY WILL ALL LEAN 39.95 DEGREES to negotiate that turn. Period.


The data on my app is very accurate. For a given lean you have selected (your comfort level lean) it will show you at what speed each corner will yield for your given lean angle.


williamr - would you like to argue highschool physics with me? Have you discovered an amendment to the laws of circular motions formula that adds in parameters for mass?
