Webby come on down you are the next contestant on the price is right.  Webby was kind enough in another post to calculate the weight of water in a 9ft diameter wheel 1 ft wide filled half full of water. That was just under 1 ton.  The wheel on the price is right's big spin is close to the size of this 9ft by 1 ft cylinder.


Webby steps up to the big spin an pulls as hard as he can and the wheel tilts at a 45 degree canter. The wheel spins 1 full time and lands on $1.00.  The crowd cheers as a ton of weight was shifted form right to left and back and not a drop of water was lifted.

Recapping the number of turns for the screw is reduced from 4 to 1. 


The difficult manufacturing of the tubes and wraps is simplified to a 9ft by 1 ft cylinder mounted at a 45 degree canter on a boat trailer axle able to support the 1 ton of weight.


Since the cylinder has only 1 wrap the water cannot become segmented into different wraps. 


The disadvantage is the water weight is spread from the hub outward on the lever, not all the weight is shifted completely to the right.

Does anyone have the formula to calculate the optimum head height?  Max Angle the lever can tilt and still be able to return to center?


There is a limit on the max angle the lever can drop and still be able to tilt in the opposite direction when the weight is shifted to the opposite end of the lever.  This is because the mass moves both down and to the right. 


The extreme example would be if you had a 6 ft lever mounted in the center of and 8ft wall.  Start with the lever horizontal and a mass balanced in the center.  Insert an imaginary line perpendicular to the lever now pointing at 12 o'clock. As the mass is moved to the right the lever rotates clockwise 90 degrees until the lever is now vertical and the imaginary line perpendicular to the lever is now at 3 o'clock.  No matter how far straight up the lever the weight is lifted it will never tilt back to the left (counter clockwise).
