yea then calculate how much the centrifugal wheel force would be on that if you pedaled let's say 150 full rotation crank spins per run.

now that should give you plenty of time to kill to figure it out and don't just type some random numbers now, kill some time and develop some brain cells for real.

Energy forces need much more information than that...

Raidus (meters) = .3302

Velocity (meter/sec) = depends on speed

Velocity (kilometer/hour) = same as above

Mass (kg) = depends on rider

RPM (revolutions/minute) = depends on speed

Actually the amount of crank revolutions per run would have nothing to do with the formula for centrifugal force.

But if you want an answer..

if:

Raidus (meters) = .3302

Velocity (meter/sec) = 8.9408 (20mph)

Velocity (kilometer/hour) = 32.18688

Mass (kg) = 4.5359237 (10 lbs. rotational wheel mass)

RPM (revolutions/minute) = ok explination on this one...

Circf. of mtb wheel 81.64"

63,360in./mile

at 20 mph your wheel will cover 776.1 rev./mile which means your wheel will cover .333 (1/3rd) of a mile. That means your wheel is spinning at 258.4413 RPM

then:

Centrifugal force (in newtons) = 1098.0988376284552

or 246.862439953226 pound-force
