200M track and field reach number formula

18 m (two semi-circles long) 200 m (two straight segments long) This is the algorithm of the first pass.

The algorithm of the second lane is the same as that of the first lane, but the number obtained by adding the width of the runway in meters to the original radius minus 200 meters to get the lower number is the number of extensions. According to the starting point of your runway, it should be placed in the straight section, so just measure the number of extensions. If you start in a corner, you have to calculate the arc length as the chord length, that is, how big the arc is to how many angles, and how many angles are to how long the strings.

I can tell you the formula.

The number of forward stretches refers to the number of forward stretches in track and field competitions, in order to make the distance run by athletes equal, the starting point of the outer road should be moved forward, and the distance moved forward at the starting point is called the number of forward stretches when calculating and measuring. In athletics, only the 200m, 400m, 800m, 4 100m relay, 4 400m relay and 400m hurdles have a number of strokes. (The starting line is not on one line).

The professional term "distance between the starting lines" is called "the number of stretches", simply put, the number of stretches refers to the number of stretches that the starting line is not in a straight line, in order to make the competition fair, it is necessary to calculate the direct distance of each starting line, that is, the number of stretches.

The calculation formula is: the number of starting point extension The length of a curve on an outer road The length of the first curve is 2 r+(n-1)d+.

Taking 400 meters as an example, the difference ratio of two adjacent runways can be calculated by using 2 straights + circumference to find the perimeter of the two adjacent runways, and then subtract each other to find the number of meters of the difference between the two adjacent runways, that is, [2 p (m.

Therefore, the number of lunges at the starting point of the outer ring of the semicircular field is not related to the radius of the site (r), but is related to the size of the width of the lane, and the wider the lane, the larger the number of extensions.

Summary. Hello, I am glad to answer for you, in track and field competitions, in order to make the distance run by the athlete equal, the starting point of the outer road should be moved forward The distance moved forward at the starting point is called the number of stretches forward when calculating and measuring

The calculation formula is: the number of starting point extension The length of a certain outer curve The length of the first curve is 2 r+(n-1)d+02]-2 (r+

The number of the starting point of each road in the outer circle of the semicircular field is not related to the radius of the site (r), but is related to the size of the width of the lane The wider the lane, the greater the number of reach.

For a track and field field of 200, find the number of stretches for a 200-meter run.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately

Hello, Spring Banquet Cha is happy to answer for you, in the track and field competition is, in order to make the distance run by the athletes equal, the starting point of the outside road should be moved forward The distance moved forward at the starting point, when calculating and measuring, is called the number of stretches

The remainder formula for calculating the common dress is as follows: the number of the front dress and extension of the starting point of the hall defect The length of the first curve of a certain outer road The length of the first curve is 2 r+(n-1)d+02]-2 (r+

The number of the starting point of each road in the outer circle of the semicircular field is not related to the radius of the site (r), but is related to the size of the width of the lane The wider the lane, the greater the number of reach.

If it is a 200-meter track, the second lane will be extended forward, followed by the tiring swim Bogami. God is auspicious. m

Summary. How to calculate the number of protrusions:

1) Calculation method of the number of starting point extensions:

a.Subtraction (difference method): ln=cn-c1

b.Induction Formula:

ln=mπ[(n-1)

ln=mπ[(n-1)

Note: LN represents the number of forward extensions at the starting point of the nth road, and M represents the number of curves (number of curved sections).

n represents the pass number and d represents the width of the lane.

N represents the cut difference, and C1 represents the first curve to calculate the line length.

cn stands for n curves and calculates the line length.

ln=cn-c1

2π[r+(n-1)d+

2π[(n-1)

For example, the number of 400m starting point extension.

l2=2×l8=2×

L400m starting point extension = 2 [(n-1)

How to determine the number of starting line stretches for the 400-meter run in the 200-meter track and field.

Hello, I have received your question and am now inquiring about the relevant information for you. Please wait a minute or two and we will answer the question right away.

This is a small calculation.

How to draw the 200-meter track and the number of forward extensions - people usually put the number of 200m and above (including hurdles. Relay Race) and Split Lane Running, in order to make the distance run by the runners in each lane equal. It is necessary to place the outer road (2-8) at each point (starting point.

Column sites. The position of each point in the relay area is moved forward within the lane, and the distance of this forward movement is collectively referred to as the number of extensions.

Cause: Calculation of line length from curves. It can be seen. The larger the radius of the outer Dao Danming cherry blossom mold bush curve, the larger the calculation line, so we say that the number of forward extension is due to the increase of the radius of the curve and produces the Huai circle.

Calculation method of the number of extensions: (1) Calculation methods of the number of starting points: a

Subtraction (Difference Method): ln=cn-c1bInduction Formula:

ln=m [(n-1)Note: ln represents the number of forward extensions at the beginning of the nth road, m represents the number of bends (the number of curved sections), n represents the number of passes, d represents the width of the lane, n represents the cut difference, c1 represents the length of the calculation line of the first curve, cn represents the length of the calculation line of the n-way bend, and the calculation line length ln=cn-c1=2 [r+(n-1)d+Example: 400m, the starting point of the forward extension, the number of wild eyes.

l2=2 Number of starting point extensions=2 [(n-1)

Summary. There is a formula for the number of curve extensions in the 200-meter run: cn=2 [(n-1)cn represents the number of forward reaches in the nth lane, n represents the number of passes other than the first lane, and d represents the width of the lane.

From the formula, a 200-meter run with a lane width of meters can be calculated.

What is the number of 200m standard runway reaches?

The 200-meter run has a formula for the number of forward stretches in the corner: cn=2 [(n-1) cn is the number of forward stretches in the nth lane, n is the number of passes outside the state of the first lane, and d is the width of the lane. From the formula, a 200-meter run with a lane width of meters can be calculated.

The radius of the runway is 18 meters, and the width of the lane is 95 cm

Won't <> with this formula

Wait a minute. Lane 1: Meter (starting point) Lane 2: Path 3: Pathway 4: Pathway 5: Path 6: Meter.

This stretch is not the same as the result you gave me, huh? I don't know what's going on.

I'm counting the third way.

The values are different. Teacher help me, really, won't you? Hold on.

The calculation method of the runway protrusion number is not troublesome.

You need to know -

1. The diameter of the circle of this track and field;

2. The runway is wide;

Counting the number of extensions is actually counting the diameter of the two channels.

If you are drawing a line in a standardized way to calculate the number of extensions, you need to - 1. Use the actual diameter of a line (the diameter of the innermost channel +) to find the circumference of the circle. (Gami is because, according to scientific research, athletes run in a row at a distance of 30 centimeters from the track.) One meter, the actual diameter is the diameter of the innermost channel +).

2. Use the actual diameter of the second track (the diameter of the first track + the width of the runway x2 +) to find the circumference of the circle. (Gami's reason is the same as above, except that runners in the second lane usually run 20 centimeters from the inside of the second lane).

With the circumference of the second way, the perimeter of the first way, and the number of extensions, I hope it can help you.
