Hey! That's what I think! In the device I'm working with the weights change their distribution too, though thats just a plus (that increases efficiency) to the main motive force of having different torque on opposite sites through asymetrical gearing. As to the centripetal stuff, if ((v^2)/r)>=g [or equivalently ((w^2)r)>=g] is true, then the weights will stay at the rim, with v=instantaneous(tangential) velocity, r=radius, w=omega=angular velocity, and g=9.8m/s^2.
: Hi Joel,
: I performed a similar experiment several years ago: 3 foot diameter wheel with free to swing weight on arm with pivot at the rim. When centrifugal force at the rim is equivalent to the force of gravity, about 45-50 RPM in my experimental setup, the weight remains immobilised at the rim.
: My conclusion was, and still is, that Bessler could not have used simple radial weight paths - particularly when you consider centrifugal force developed at the rim of his 9.3 feet diameter Draschwitz wheel rotating at 50 RPM was so much greater than gravity.
: This has led me to consider that the weights may never have left the rim of his wheel, but rather move around the rim at a constant radial distance. In this case overbalance is achieved by changing the spacing between the weights.

: : I ve done simple experiments by tying diffent weights around the perimater of a 24"plywood disk mounted on bearings. weights range from string or cord to weights aproxamatly 1 oz.,1 pound,2.25 pounds.My results are regardless of weight (string included)at aproxamatly 60 to 70 rpms all weights are fully extended (opposite axle)As the rpms drop below 50 to 60 rpms so do the weights.I would like to hear from anyone who s done simular experiments of this type with centrifical forces.
