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 question. As the wheel rotates, very slowly as to have a minimal centrifugal centripetal force affecting it, the weight in the 10 through 2 o clock position will compress the spring, as the wheel rotates further the spring un-compresses and pushes the weight back to the outside of the wheel. Question - Does this wheel require more energy to turn when compared to the identical wheel moving at the same speed (rpm) with the weights fixed to the outside so they can not move? My thoughts, no, since the energy (leverage) is lost at the top but stored in the spring and recovered on the other side as it goes back down. I am wondering if there is energy loss due to the compression of the spring, loss of leverage temporarily. Thanks for any input. I understand these are pretty mundane questions and all revolve around newtons laws of thermodynamics but some clarity or guidance and confirmation would be great.
