View Full Version : Very nice gearing program RaceBikeRentals May 22nd, 2009, 01:55 PM http://gearingcommander.com/ Looks pretty accurate to me. I'm going to measure the circumference of my BT090 and BT016 tires and plug em in. Alex May 22nd, 2009, 02:21 PM neat link! To save time, you can always measure the diameter and multiply by 3.1415927. :rotflmao: Apex May 29th, 2009, 06:10 PM neat link! To save time, you can always measure the diameter and multiply by 3.1415927. :rotflmao: Nope. You gotta do 3.14 x r^2 Diameter will give the wrong value I just got out of my college math class a while back. That stuff is hard after being out of high school for over 10 years! ztrack157 May 29th, 2009, 06:44 PM No it won't If I remember back ten years your equation will yield the area of a circle. 3.141592654 (as far as I can remember) X D will yield the circumference.

I wouldn't publicize which college, it might be embarrassing for them. :D pi * r^2 is the area of the circle, pi * D is the circumference of the circle. :thumbup: g21-30 May 31st, 2009, 03:41 PM Everyone knows that pies are round, not square! :D Apex June 17th, 2009, 10:02 AM :thumbup: I wouldn't publicize which college, it might be embarrassing for them. :D pi * r^2 is the area of the circle, pi * D is the circumference of the circle. :thumbup: lol my brain is a molten mess after that math class. We crammed so much information into our heads I'm surprised that we all passed the class! |
