(36,286 posts)but was wondering how much power was lost in each step down, and noting that the block is square, meaning that turning it would mean enough power to crush the wooden board.....so at some point I expect the mechanism to be jammed.

(8,175 posts)I wonder if a turn at that speed would just mean the shaft in the concrete rotates without moving the concrete at all.

(5,335 posts)With the inevitable slop in the gear train, the last gear is probably not moving at all. Any moving that it does will be in quick spurts as friction is overcome, and there may even be times when it moves backward. All they can really know with any precision is the average revolution rate over some very long period, and the minimum value of that period is almost certainly longer than this device will even exist.

(5,214 posts)Well, actually they can via lasers.
Physics is the way IT HAS TO MOVE and if the drill did not move, the machine is operating in a parallel universe, with different physical properties.

(101,470 posts)then its circumference is about 31cm; 200 rev/min = 0.31*200/60 = 1 m/s speed on its circumference, roughly.
So the 2nd gear goes at 0.02m/s
3rd: .0004 m/s
...
6th: 3.2 nanometres/sec. Roughly the diameter of 12 iron atoms. Or about 2mm in a week.
8th gear: the diameter of a single iron atom in about 200 seconds. Less than a micron in a week - he could have set this one in concrete comfortably, I think.
10th gear: the diameter of a single iron atom in nearly 6 days - if he ran the machine that long.
12th gear: the diameter of a single iron atom in about 40 years.
