What exactly does the term "horsepower" mean?
I m under the impression, that let s say that a car has 200 hp. Does this mean that if it had a tug-of-war with 200 horses, it would be a stale mate?

Fazaldin A say: car has 200 hp. It Does not mean that it had a power of 200 horses,

Technically, 1-horsepower = 745.7 N-m/sec = 746 Watts.
So,
Car has 200 hp = 746 x 200 = 149200 N-m/sec.

say: The term came from James Watt studying one horse doing work, that walked in circles and pumped water.
He observed it, and decided the horse could lift 33,000 lbs. of water a height of 1 foot in 1 minute.
Yes, 1 hp. was born. Its definition has changed over the years, however.

J say: The term is based upon the daily output of horses, not upon their pulling strength.
Everybody else is wrong.
-
say: Power.

Philomel say: 1 HP is defined as 550 Ft Lbs/ sec.
If you raise a weight of 550 lbs at a rate of 1 ft/ sec that is 1 HP
If you raise a weight of 1 lb at a rate of 550 ft/ sec That is 1 HP.
If " " 225 lb " 2 ft/sec 1HP.
etc.
This is approximately what a standard work horse can do in work.
