Neat demonstration Tubalcain. I was wondering what was going to happen when you tightened those bolts on the arm around the hub. Just for those who are wondering, a 2 foot 7-1/2 inch arm equals 2.625 feet. Multiplying that times the 2 pi in the top half of the equation is approximately 16.5 so the formula becomes 16.5 P N/33,000. Dividing the top and bottom by 16.5 reduces the formula down to P N/2,000. I enjoy watching your machine shop videos. Thanks.

You got it boss. Known as the Prony Brake Constant. Makeing the arm a fixed length to simplify the formula was done alot, they didnt have calculators back in the late 1700 when the brake was invented, just slide rules or good ole fashioned long division
