    How to determine the price of a stopwatch?

    then you can calculate the price of division in this way:

    First, count all the divisions from zero to the first, namely 5 seconds.

    In the picture they are 10 divisions on the stopwatch of this type.

    Then 5 seconds to divide by ten divisions and get 0,5 seconds.

    5 / 10 = 0,5

    Accordingly, the 1 division on this stopwatch is 0,5 seconds.

    2 division - 1 second and so on and so on.

    3 divisions -1,5 seconds

    4 divisions - 2 seconds

    5 divisions - 2,5 seconds

    6 divisions - 3 seconds

    7 divisions - 3,5 seconds

    8 divisions - 4 seconds

    9 divisions - 4,5 seconds

    10 divisions - 5 seconds.

  • To determine the price of the stopwatch division, it is necessary to find the two nearest lines of the scale, the value of the value must be indicated beside them. Subtract from a larger value what is less. Then the resulting number is divided by the number between the values ​​of the divisions.


    Strokes from 20 to 25 from. The interval between them is 10 divisions. Accordingly, the division price in this case will be 25-20: 10 = 0,5 sec. And after we learned the price of division, we can find out the time that the given stopwatch shows.

    How to determine the price of a stopwatch?

  • Having a stopwatch, you can use the help of not tricky calculations to determine the price of division of this stopwatch.

    For example, if there is a "; 0quot; and after a few divisions the digit "quot; 5quot; follows, then to determine the price of division it is necessary to calculate the number of divisions between these digits. If it turns out 10 divisions, then 5-0: 10 = 0,5. The price of dividing such a stopwatch 0,5 seconds.

    How to determine the price of a stopwatch?

  • In the stopwatch version proposed below, we see that the main dial has a maximum indicator of 60, which means that there are 60 seconds in one minute (as we all are used to thinking). It happens that the stopwatch consists of a hundred divisions, respectively, seconds are calculated in hundredths.

    So, if we start from the figure below, then we need to calculate how many parts the sector is divided between the two nearest numbers. Then, the difference between these numbers divided by the number of divisions obtained - this will be the price of division.

    How to determine the price of a stopwatch?

  • On the dial, any stopwatch has numbers. As a rule, the total number of divisions of the whole 60 is the full circle, by the number of seconds in a minute. In this case, one division will be one second.

  • Manual mechanical stopwatches are almost never produced, but in everyday life they are still encountered. They are of two kinds. The first is with a scale capacitance for a second hand in sixty seconds. The price of division in such stopwatches is 0,2 seconds (the error in determining the time interval is half the scale division, that is, 0,1 seconds). The second - with the capacity of the scale for a second hand in thirty seconds. The price of division in such manual mechanical stopwatches is 0,1 seconds (the error in determining the result is 0,05 seconds). In recent years, twenty such stopwatches are practically not used, since a lot of hand-held electronic stopwatches are produced, which determine the time to within 0,001 seconds and do not have a scale at all. The truth when using such a stopwatch should take into account the reaction of the person-timekeeper. And it in a normal person is approximately equal to 0,2 seconds, that is higher than the error of the most inaccurate mechanical stopwatch.

  • In fact, this is not so difficult as some describe it.

    If the scale, for example, up to 5 seconds, is divided into 10 divisions, then it is clear that the division price is half a second.

    This is determined simply. It is necessary to divide the number of divisions of the scale into the known time (seconds). As a result, the price of dividing the stopwatch (whether 0,5 sec, 1 sec or other value) will be obtained. The main condition is to know the time, that is, there must be a specific mark in 5 or 10 seconds.

    How to determine the price of a stopwatch?

  • Так же, как и в другом измерительном приборе, полагаю. Из большего значения вычитаем меньшее и делим на количество делений между ними. Например, 60 сек - 55 сек = 5 сек. Полученное делим на 10 и получаем цену деления.

  • In order to determine price of division stopwatch, you first need to take two adjacent strokes (dividing), opposite which there are numbers. Typically, the stopwatch is designated as follows: 5 - 10 - 15 - 20 and so on.

    Let's take the divisions with the numbers 10 and 15. From the larger we take less: 15 10 and get 5c.

    We have to divide this result into the number of divisions that are located between them: 5 split 25 and get 0,2 seconds.

    If the divisions are 10, then 5 is divided into 10 and we get the price of milking the stopwatch XNUMx sec.

  • To determine the price of division, with not only a stopwatch, but also, for example, a thermometer, an ammeter, or a ruler, you should adhere to only two non-complex calculation rules.

    How to determine the price of a stopwatch?

    So, in the displayed stopwatch, the division price is 0,2 seconds, because (10-5) / 25 = 0,2.

  • Option two.

    Look in the passport.

    Calculate, dividing the known time by the number of divisions.

  • How to determine the price of a stopwatch?

    Take for example an example of such a stopwatch, it has many divisions and therefore it is very difficult to determine from it.

    Firstly, according to 60 to 5, the biggest divisions are five. It turns out that every division is a second. But between them there is even smaller. Summarize them - get 25 in five seconds. 5 / 25. Or 1 / 5 seconds. But if it is in the middle, then 1 / 2 seconds.
