How many horses
This horse can do 22,000 ft-lb a minute. When we figured out that it can do as much as 1.5 ponies, we multiplied the power of a pony (22,000 ft-lb of work per minute) by 1.5 and called it one horsepower (hp). And this horse was like an engine. Using the word horsepower it probably made people think of the old days.
This is the kind of horse that can pull a lot.
Horse pulling something
This horse is pulling something really heavy.
These are the kind of ponies that this one horse can be.
Now these days.
Now these days people just go out and buy cars. They don't think about the money they spend, all they do is want to go places. And people use trains besides horses. I think people should go back in time and do what they used to do.
