Anonymous users2024-02-07The innermost circle. The standard runway has a total length of 400 meters, the curve of the runway is semicircular, and the radius of the innermost ring is 36 meters, each runway is wide by meters, and there are 8 runways.
It is known that the total length of the standard runway is 400 meters, which refers to the length of the innermost runway, and the radius of the innermost ring is 36 meters, so you only need to find the sum of the perimeters of the two semi-circular curves of the innermost runway, and then subtract the sum of the perimeters of the two curves from 400 meters to get the length of the straight.
Rice. The total length of the fourth runway is obtained by adding the sum of the two semicircular curves of the fourth lap plus the sum of the two straights, and the length of the straight is already known in front of us: 87, so the total length of the fourth runway is: 87 2+2

Athletics field standards: The IAAF Handbook stipulates that the standard semi-circular track and field track is 400 meters long and consists of two straights and two curves. At present, international and domestic track and field competitions usually use the following types of track and field fields.
1. The track and field field with a radius of 36 meters along the inner protrusion: the calculation radius of one lane is meters, the length of the calculation line of one curve is meters, and the length of the calculation line of two curves is meters. The length of one straight section is meters, the length of two straight sections is meters, and the length of the calculation line is 400 meters.
Such as Beijing Workers Stadium, Liaoning Anshan Stadium, Shanghai Hunan Stadium, etc. 2. The track and field field with a design radius of meters along the inner protrusion: the calculated radius of a lane is meters, the length of a curve is 120 meters, and the length of the calculation line of two curves is 240 meters.
One straight section is 80 meters, two straight sections are 160 meters long, and the length of one lane and one circle calculation line is 400 meters. Such as the track and field field of the Beijing National Olympic Sports Center, the track and field field of the Shenyang Sports Center, and the track and field field of the 24th Olympic Games in Seoul, South Korea. 3. The track and field field with a design radius of meters along the inner protrusion:
The calculated radius of a lane is meters, the calculated line length of a curve is meters, and the length of the calculated line of two curves is meters. One straight section is meters, two straight sections are meters long, and the length of the calculated line is 400 meters. Such as Dalian Stadium, Guangzhou Olympic Athletic Stadium, Changsha ** Stadium, 23rd Olympic Games Los Angeles Athletic Stadium, etc.

Anonymous users2024-02-05The difference is about 53 meters.
A standard 400-meter runway, with the first (innermost) track being 400 meters long, and the outer ring of the two adjacent runways being one meter longer than the inner ring.
The 400-meter standard runway should consist of two parallel straights and two curves of equal radius. The standard runway is 400 meters long, there are 8 runways, each runway is 87 meters wide, the straight track is 87 meters long, the curve of the runway is semicircular, and the radius of the innermost ring is generally 36 meters.
Length of the first track: 87 2+2 400 m.
Eighth length: 87 2+2 453 m.
So the difference is about 53 meters.

Anonymous users2024-02-03What is the difference between the outer and inner rings of a standard 400m runway? The standard runway has a total length of 400 meters, the curve of the runway is semicircular, and the radius of the innermost ring is 36 meters, each runway is one meter wide, and there are 8 runways. And we know that the radius of the innermost ring is 36 meters, so you only need to find the sum of the perimeters of the two semi-circular curves of the innermost ring runway, and then subtract the sum of the perimeters of the two curves by 400 meters to get the length of the straight.
174 2=87 meters, the total length of the fourth runway is obtained by the sum of the two semicircular curves of the fourth lap plus the sum of the two straights, and the length of the straights is already known in front of us: 87
First: 87 2 + 2 400
Second: 87 2+2 408
Third: 87 2+2 415
Fourth: 87 2 + 2 423 m.
Fifth: 87 2+2 430 meters.
Sixth: 87 2+2 438 meters.
Seventh: 87 2+2 445 meters.
Eighth: 87 2 + 2 453 m.

1. The first thing to pay attention to when writing a refueling manuscript is to be easy to understand, because the manuscript is for listening, not for reading, and there is no time to savor it, whether you can understand the intention of the refueling manuscript is only at the moment of hearing, so when writing a refueling manuscript, it must be easy to understand, unpretentious, so that the reader can read it smoothly and the audience can sound effortless. >>>More
