wanting to attach this 3 speed hub with 28 spokes i can only find 36 or 40 spokes on 24 inch wheel or how can i make what i have fit by tapping them in but how mathmatically
Reply:
28 spoke rims may exist in the size you want, you just have to look hard to find them. Most stores have catalogues from several suppliers that they deal with, these suppliers carry various makes and models of rims along with selections of the various length spokes needed to build a complete wheel

Since we are talking ANGULAR velocity here [not linear], the diameter of the big wheel in irrelevant.
The pedal-wheel height is 8 inches, and the hub of the bicycle wheel has a diameter of 3 inches. This means every time you do one rep of the pedal wheel, the front wheel must move 8/3 = 2.6666… times. To get 90.0 rpm for the front wheel, you only have to spin the pedal wheel 90/2.6666= 33.75 rpm.
It looks like there is only 1 significant figure…so I guess 30 rpm is technically the most precise answer you can give.
1 = 22,
2= 16
3=3
4=(x+y+z) / 3
5 = 1/5
6 = 100 meters.
7 = (2,-2) & (1,5)
8 =12
9 = 9pm.
10 = 2400
12 = 0
14 = 3.5
15 = 7(21) / 4
wow thats about as kool as a kicker l7
How can you people live with imperial measures?

Length of ride to school: 5280 ft.
Length covered by one revolution: 3.14*d
Amount of revolutions: 5280/(3.14*d)
For Jesse: 5280/(3.14*d) = 5280/(3.14*(20/12)) = 1008
For Nathan: 5280/(3.14*d) = 5280/(3.14*(24/12)) = 840
1008 – 840 = 168

There's probably an easier way, but here's how I would do it.
Circumference of the wheel is about 75.39816 inches.
25 miles is 1584000 inches
1584000/75.39816 = 21,008.47 is the number of wheel rotations per hour at 25 mph (not the number of radians) depending upon the accuracy of pi that you use.
There are 6.28 radians in a circle, so divide 21,008.47 by 6.28 and you have the number of radians per hour = 3345.2978
