A snad naposledy na dlouhou dobu vás budu ještě otravovat s překladem jedné věty.Zase překládám článek „How Horsepower Works“ a Hned první věta mi nedává moc smysl, nebo trošku dává ale nevím jak to přeložit : Chances are you've heard about horsepower.
Celý text „How Horsepower Works“ pro představu o čem to je:
Chances are you've heard about horsepower. Just about every car ad mentions it.
But what is horsepower, and what does the horsepower rating mean in terms of
performance?
The term horsepower was invented by the engineer James Watt. Watt lived from
1736 to 1819 and is most famous for his work on improving the performance of
steam engines. We are also reminded of him every day when we talk about 60-watt
light bulbs.
The story goes that Watt was working with ponies lifting coal at a coal mine,
and he wanted a way to talk about the power available from one of these animals.
He found that, on average, a mine pony could do 22,000 foot-pounds of work in a
minute. He then increased that number by 50 percent and pegged the measurement
of horsepower at 33,000 foot-pounds of work in one minute. It is that arbitrary
unit of measure that has made its way down through the centuries and now appears
on your car, your lawn mower, your chain saw and even in some cases your vacuum
cleaner.
What horsepower means is this: In Watt's judgement, one horse can do
33,000 foot-pounds of work every minute. So, imagine a horse raising coal out
of a coal mine as shown above. A horse exerting 1 horsepower can raise
330 pounds of coal 100 feet in a minute, or 33 pounds of coal 1,000 feet in
one minute, or 1,000 pounds 33 feet in one minute. You can make up whatever
combination of feet and pounds you like. As long as the product is
33,000 foot-pounds in one minute, you have a horsepower.
Horsepower can be converted into other units as well. For example:
1 horsepower is equivalent to 746 watts. So if you took a 1-horsepower horse
and put it on a treadmill, it could operate a generator producing a continuous
746 watts.
ještě jednou díky
moc za všechny rady!!!
