yes, when I say energy to turn the wheel, it could be generic, a motor, wind, rolling down a hill... some sort of energy is needed to turn it.
skatche- regarding the centrifugal effects. yes once rpm is up a bit, no movement would occur as the weights or anything that can move will move to the...
That's interesting that you point that out. Besslers wheels and these "devices" is what I was evaluating. Not that they could ever work, but do they actually require more work to turn because of what was happening inside them.
regardless to what happens inside the wheel? My understanding is the same, almost zero energy to "turn" the wheel once it is up to speed, minus bearings, wind and friction. My focus is on what happens to a weighted wheel, is that still the answer, because it is a wheel and whatever happens on...
Good afternoon and thank you all that helped with the other wheel. It did in fact loose energy from the slide as the position once the movement happened, the energy was lost as the leverage was lower once the movemnt happened and therefore not recoverable.
Which leads me to this wheel and...
Thank you all for your input. But my dilemma is the same. Which one is correct? You both make the same observations I make with 2 totally different results. I am trying to figure out a simple way to test / observe this to generate an answer.
- take the wheel in a the first position, the slide is pulling the weight down, turn the wheel 90 degrees clockwise, the extended weight is at the 9 position and slides so that the opposing side is extending out toward 3 as it turned. that side would then fall. It would not exceed the energy to...
so your saying if the slide can move, it would take more energy to turn than if it was fixed in one position? Wouldn't the fact that when it slides at @ 9 oclock and 3 respectively, it would balance itself? Maybe there would be a loss of energy in friction in the mechanics of the slide.
that is kind of where I am confused. once the wheel makes one full rotation, wouldn't it balance out? you kind of get a bonus as the weight is on the falling side and getting the benefit of gravity??
as seen. a wheel with a part that would slide as the wheel rotated. All the research states that there is no positive energy gain or net torque gain, my question is does the wheel pictured require more energy to rotate than if the slide weight was fixed? I think that there is no difference but I...
Good afternoon and thanks for reading. I have been in a discussion with a friend and we are trying to get to the bottom of it. It all started when looking at overbalanced wheels and shifting mass wheels. I know that they will not turn themselves, but do they have a negative torque applying to...
