[Closed] Why are 180mm rotors more powerful than 160mm?

HOW DID THIS GET TO FOUR PAGES?

Only skimmed the junk but there's more made-up 'science' here than in a creationist's textbook.

LOCK THIS THREAD PLEASE, IT IS DOING MY HEAD IN!!

pdw yeah I understand that, but look at the time taken to stop. In the work done equation there is a time term t, if you reduce the number of rotations by using a bigger disc, then it takes less time (or increase by using a smaller disc.)

I'm sure no one will thank me for resurrecting this thread but...

There shouldn't be a time term in the work done equation. In the equation you wrote, the time terms cancel out. It really is just force * distance, which in the case of a disc is force * radius * 2 * pi * number of revolutions.
