A horse-power is 33,000 ft.-lbs. per minute. They came up with that number long ago by testing good draft horses. A good draft horse working his heart out, with enough leverage, could hoist water out of a mine shaft at a rate of lifting 33,000 lbs. of water up, at a rate of one foot per minute. OR he could raise 16,500 lbs. at a rate of 2 feet per minute. OR he could raise 8,250 lbs. 4 feet per minute. Conversely, the old boy could also lift, say 100,000 lbs. at a rate of 33/100 = 0.33 feet per minute. Old boy could lift the Empire State Building, but real slow, like 2013 and most of 2014. Old boy cranks out the same power HP, but his leverage and time are directly related. You want him produce a lot more leverage, it'll take him a lot more time.

I’m par
