D's dicussion on overcoming weight and diameter

I was editing my other post, but the thread was locked right in the middle of some fairly interesting discussion on weight vs diameter.

EDIT: D's facts are facts, but he gave me three sentences out of the book. I would have to go look it all up to lay it ALL down. I have other things to do. He is talking of torque overcoming the weight and/ diameter of the wheel (mass). He is speaking in theory that it doesn't matter where the weight is. I don't remember that being practical, not when considering you are moving a round mass by an axis running though its center. The further the weight is away the center point, the more torque is used to get it going. Think how counterweights on cranks work. They wouldn't be the same if you kept the same amount of weight and concentrated it closer the center of the crank shaft.

Tie two lead ***** to short string. Tie a lead ball in the middle of the string and tie another lead ball, twice the wright, on the end. Spin it. Notice the force it takes to get it going and the force it has when you quit applying the motion. Next reverse the position of the ***** and spin.

Both have the same weight on the string, but the position of the weight makes a drastic difference on the force

Given enough tequila, I might do the fat folds on the left one.

judgin by the replies thus far, i think everyone agrees this is a fruitless thopic

i didnt see any discussion in the first thread. what i saw was D. pointing out that you left many variables out of your examples. i also noticed that you have done the same thing here.
there are far, far too many variables between the mass of your 24" wheel/tire combo and the diameter of maurices 35's to try and prove anything through the simple examples you have posted.

now i could dig out my old college books and drudge thru a couple days of equations, but what would it be worth? maybe you can grab your books(im sure they are more accessible than mine) and go ahead and show us the equations?
