Good Evening to all,
I have been working on the following problem for the past several days and have finally come to the end of my rope. I hate to admit defeat but I do need some help. I'm almost certain I'm simply missing something that's embarassingly simple...
This is the problem exactly as it appears on the page:
----------------------------------------------------------------------------
2. Centrifugal force is given by the following equation:
F = m [tex]\omega[/tex]^2 r
Where F = Centrifugal force
m = mass
[tex]\omega[/tex] = angular velocity
r = length of radius
A student told me the other day that centrifugal force on a mass m kg, rotating at an angular velocity of [tex]\omega[/tex] rpm and at a radius of r feet, is given by the following equation:
F = 3.342 x 10^-3 m [tex]\omega[/tex]^2 r [Newtons]
Are both equations correct? Explain?
----------------------------------------------------------------------------
I know that this means I need to take the F equation, break it down into its base SI units and build it back up taking the meters to feet and seconds to minutes conversion into consideration.
I know that the conversion for meters to feet is 3.28084. What am I missing?
