Hi, I was wondering if there was a simplified formula for working out
centrifugal force with a constant mass rotor.
Unfortunately I can't make sence of it, what is the constant 2900 derived
from?
When using, F= MV^2/r
F= force
M= mass
V= velocity
r= radius
By summing each calculation -- say at r=1m, 'X'm/s,M=1Kg
r=2m
'X'm/s,M=2Kg
and so on .(the smaller the increments the better)
The end result is not even close to the formentioned formula.
Where have I gone wrong?

Cheers Cam
(excuse the metric system)

om...
The centrifugal force generated by a rotor blade
is (W*r*rpm^2)/2900 W is the blade weight. r is the distance from
the hub center to the CG of the blade
