Why Bessler's wheel was able to accelerate to full speed in three turns.

Further to my last blog,I posted my thoughts on http://www.besslerwheel.com/ forum, about something that to me seemed to be illogical; the fact that the torque appeared to be greater for a one inch movement horizontally on a smaller wheel than on a larger one - and in the process found myself corrected. The torque itself remains the same but the acceleration of the overbalancing effect due to a one inch difference between the two positions horizontally, is greater on a smaller wheel than on a larger one - or when the action takes place closer to the axle. So although my means of getting there was wrong my conclusions were correct.

I had compared the speed of reaction on two rods balanced on a pivot at their mid-point. One rod was two foot long and the other was six foot long. In each case the same weights were attached, one at the end of the rod, the other, two inches inwards towards the centre of rotation, at the other end. The torque was the same in each case but the shorter rod accelerated into its unbalanced position much quicker. This suggested to me that, with the limited range of movement available from my mechanism, it would be react to imbalance more quickly if I placed the weight as close as possible to the axle.

This may explain why Bessler's wheel accelerated to full speed in just three turns - because although the weights moved a small amount, they did so close to the centre of the wheel rather than near the edge. I believe that this is a useful piece of information and one that is generally ignored or perhaps people are unaware of its significance. I certainly didn't consider it of any importance, but when I found I was limited by space for the mechanisms and sought a way around it, this fact supplied not only the solution to the problem but will, I believe, also deliver an improved reaction to the movement of the weight.
