感謝大大^^ (跪謝...)
> (1) Because rpm is revolution(s) per minute,
> rpm = (w/(2Pi))*60 where w is radian/sec
> Thus, w=(Pi/30)*rpm
> (2) a=rw^2 (because a=(v^2)/r, & v=rw)
> (3) RCF (relative centrifugal force) is defined as
> RCF= (a/g)= (rw^2)/980 = {r[(Pi/30)*rpm]^2}/980
> =1.119* 10^(-5) * (rpm)^2 * r
> done!
