It doesn't have to be a turning shaft. If you can throw 55 ten pound
bricks over a 10 foot wall in one second your a one horsepower engine.
Work
is force times distance, Power is the rate at which work is done. If
someone else throws the bricks over in 5 minutes samework, less power.
If I remember correctly ( which I seldom do) Watt used a unit of horse
power
because mine owners used horses. If your selling steam engines to replace
horses it was handy to tell the customer that it would replace X horses.



Maybe I am just a drunk Irishman throwing bricks over a wall, while taking
alternate swigs from my everlasting Guinness bottles?

Whatever, I will accept that. It was quite coherent. After re-reading what
I wrote, I am not entirely sure I wrote what I meant anyway.
