If the track is 400 meters, how much is the difference between the positions of the two adjacent sta

There are two semicircles on a 400-meter runway, and the two semicircles have equal radius, which together form a circle.

The radius of the innermost circle (i.e. the first lap) is meters, then the two semicircles of the 400-meter runwayCircumferenceYes: 2* The radius of the second lap is meters, then the circumference of the two semicircles of the 400 m runway is 2*( = m, so a circle of 400 m on two adjacent runwaysStarting lineThere should be a difference in meters, and if you run 200 meters, the starting line should be in meters.

Related Notes:

Runway refers to the sports field used for running and speed skating.

Racing roads, such as racing cars, also refer to long strips of land on airports for aircraft to take off or land. The runway can be asphalt or concrete, or flattened grass, mud or gravel floor.

The length of the runway determines the size and type of aircraft that can take off and land to some extent, of course, the strength of the runway pavement (usually expressed in PCN values), the width of the runway and the altitude of the airport.

There is also an impact on this. In general, the larger the aircraft, the longer the runway length required for takeoff and landing.

How many meters does the starting line of each track differ?

A 400-meter race is held on the 400-meter circular running track of the old first track, which is 1 meter wide and adjoins the starting line of the two Hanshi runways.

Difference: The second lane is ahead of the first starting line: [(2-1)*m.

The 3rd lane is ahead of the 2nd starting line: (3-2)*1*2 = meters.

The 4th lane is ahead of the 3rd starting line: (4-3) * 1 * 2 = meters.

The circumference of the first lane of the standard semicircular track and field field is 400m, and its radius has different design schemes, and the commonly used is 36m

Wait. (1) Calculation of runway perimeter (1st lane perimeter).

1. Calculation of curve lengthThe sum of the length of the two curves in the semi-circular track and field field is exactly equal to the circumference of a circle. According to the circumferential formula.

c = 2 r, then the length of the first two curves (calculated line length) is:

2 A curve is long.

2. Calculation of the length of the straight section.

Two straight lengths = full length of the runway - two curves length.

400m –

A straight segment is long.

3. The total length of the runway is calculated as the total length of the runway = two curves + two straight sections.

400m (three) Calculation of the length of each lane separation curve (taking the width of the lane as an example).

According to the circumferential formula c = 2 r

cn=2π[r+（n-1）d+

C represents the circumference of the curve, N represents the number of passes, R represents the radius of the field, and D represents the width of the lane).

3) Calculation before the starting line is extended.

If both runners run their own lane for 1 week, the runner in lane 2 will run more than the runner in lane 1.

In order for the 2nd lane to be equal to the distance traveled by the runner running the 1st lane, the starting point must be extended some distance forward. Direction.

The distance of the front extension is called the number of front stretches of the starting line.

The starting line is calculated by subtracting the length of the first lane from the length of the first lane. That is, the number of starting line extensions of the road.

The formula is as follows: wn=2 [r+(n-1)+

The 400-meter race is carried out on the 400-meter circular track, the runway is 1 meter wide, and the starting line of the two tracks is different from the two tracks

The second lane is ahead of the first starting line: [(2-1)*m.

The 3rd lane is ahead of the 2nd starting line: (3-2) * 1 * 2 = meters.

The 4th lane is ahead of the 3rd starting line: (4-3) * 1 * 2 = meters.

Difference: meters (because the two corners are a circle, the straights are the same, and the curve difference is the difference between the circumferences of the two circles) with a 400-meter standard runway radius of 36 meters, and the width of the runway is meters The circumference of the first lap of the runway is 2*, and the circumference of the second lap runway Pikey is 2*

2 c, the diameter of the runway in the inner ring is b, and the width of the runway is cThe difference between the first lap and the second lap is b- (b+2c)=2 c, and the difference between the second lap and the third lap is (b+2c)- b+4c)=2 c, and the difference between them can be obtained by 2 c

Summary. There is a trick in this problem, the distance between the two people is equal to = runway width, pi, and number of curves. Therefore. Hope it helps, hope, thank you.

There is a trick in this problem, the distance between the two people is equal to = runway width, pi, and number of curves. Therefore, the destruction of the rough refers to m) fiber matching. Hope it helps, hope, thank you for the early stool.

The final answer is yes?

That's right. Thank you.

Good bye. Good bye.

Rice. For a 400-meter running race (400-meter track), the width of the track is meters, and the starting lines of the two adjacent tracks should be separated by meters.
