Is this possible with high power output approx 80hp. and what kind of cost do you mean by V.expensive? Do you know of a company which can provide these generators with the advanced circuitry.

If good motors make terrible generators, can good generators make good motors. I haven't decided on the electric motor, just trying to figure out some good ideas. and what I need to do. I am trying to develop a direct drive ( or other type of gear box etc, depending on what is needed) to a...

theoretically I believe this is possible: basically I am trying to decide if I could use an electric motor as a generator to charge a battery source, and when needed use it as a motor as well. I think the only issue is the rpm's which it is operating at, to get the most...

alright. Thanks very much.

determining that force acting on the string? by the object, or determining how much force the object is putting on the string. either way.

how do you go about doing that?

From reading other forums, I have been confused on the fictional meaning of the force. I was just wanting to know how to determine the outward force which I thought was called centrifugual force. In your example with the string, wouldn't there be a stretching force on the string towards the...

To determine the centrifugal force, would it be the same as the centripetal? equal opposing reacting force?

So for example: you have an item which ways 5lbs which would equal 5/32.2 = .15528 slugs. your velocity is 50ft/s and your radius is 2ft. So according to this equation. Fc = mv²/r = mω²r Fc = (.15528 slugs*50ft/s ^2)/2 ft = 194 (lb*f*s^2/ft)(ft^2/s^2)/(ft) = 194 lb right...

What units would that be, I would initially think lbs. but it how does the ft/s cancel. lbs * (ft/s)^2/ft = lbs*ft/s^2 that can't be right. what am I forgetting?

Simply put I just would like to find the force of a single object rotating in a circle relating to weight, RPM or any omega, and distance from center. Would the equation below work for what I am trying to do. Or do I need to derive something, If this is the case, I could use some help.

I understand the rotation, I would just like to know what the force of that object would be at different points from the center as it rotates. Like when you twirl a rock on a string around your finger, as you bring it in I'm sure the force changes and so does the speed. Am I making any sense...

The centrifugal force of an object based upon the radius, weight or mass of the object. In the long run I would like to calculate the force exerted by the object at any point in the radius of the circle while rotating around at a constant velocity. In this case would we now be talking...

Sorry I'm a little lost on figuring out the derivative. How do you set that up?

what is mks. how do you perform that equation?
