Rotor Tip Weight (Centrifugal Force)

AI Thread Summary
To determine the centrifugal force at the tip of a 35ft diameter rotor rotating at 392rpm, the formula F = m * ω² * r can be used, where F is the centrifugal force, m is the mass, ω is the angular velocity in radians per second, and r is the radius. Factors such as blade thickness and weight may also influence the overall dynamics but are not directly part of the centrifugal force calculation. The pilot's skepticism about the rotor tip weight being measured in tons highlights a common misconception in rotor dynamics. The discussion emphasizes the importance of understanding the physics behind rotor mechanics. Accurate calculations are essential for safe and effective rotorcraft operation.

What formula would one use to determine the centrifugal force at the tip of a rotor of 35ft diameter, rotating at 392rpm?
Would any other factors be necessary, such as blade thickness, weight, etc?

A pilot I work with doesn't believe the weight at the rotor tip would be measured in tons.
I was given the formula many years ago by an instructor, but it has been long forgotten. :-)

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
