How does the tachymeter work?
A tachymeter is designed lớn measure speed. Và it actually works very simply. Most importantly, you must have a distance of exactly 1,000 meters with a start & end point. The moment a vehicle passes the starting point, turn on the chronograph of your watch. When the vehicle then passes the end point after 1,000 meters, stop the stopwatch.
And now?
At this point you know how fast the vehicle has driven over a distance of 1,000 meters. With this data you can calculate in a very complicated way how fast the vehicle has driven. But the tachymeter makes this unnecessary. The second hand of your watch points to a point on the tachymeter. This is the average tốc độ that the vehicle traveled over the kilometer you measured.
Measuring speed, an example:
In forty seconds, the measured vehicle travels exactly one kilometer. The second hand of your watch not only points khổng lồ 8, it also points to lớn a number on your tachymeter: 90. So the vehicle was traveling on average 90 kilometers per hour.
Is that right?
We"re going to check it out. If you have covered 60 kilometers in an hour, then on average you have driven a kilometer every minute, since an hour consists of 60 minutes. If you drove 90 kilometers in one hour, how many seconds would it take you to travel one kilometer? Divide 60 (minutes) by 90 (kilometers). That"s 0.66666666667, or 2/3. 2/3 of a minute is 40 seconds và it says that the vehicle was traveling on average 90 kilometers per hour.
Disadvantage of a tachymeter
A tachymeter has a major drawback. In principle, you can only measure speeds from 60 kilometers per hour. Some watch brands have found a solution. For example, they also let you return to lớn 55 & 50 kilometers per hour on the right side of the 12. But for this you use more than sixty seconds.
