Dimenzije atletskega stadiona

Iz prve roke ti pove točne mere: steze morajo biti široke 1,22-1,25 m.

Dolžina prve steze je izmerjena 30 cm od notranjega roba (da je točno 400 m), vse ostale steze pa so izmerjene 20 cm od notranjega roba. Črte so debele 5 cm, ampak so upoštevane v širino steze na notranji strani (v principu tek po črti ni diskvalifikacija). Še to, stadioni nimajo fiksnega krožnega radija (npr. ljubljanski je večji od celjskega).

Računat se mi pa ne da, ampak v naših krogih velja, da je en krog po osmi stezi 450 m.

Tnx!

Če tole drži, potem je glede na zgoraj napisane mere, osmi krog dolg 453 m.

; "It doesn't matter how long the straights and turns are. It doesn't matter if your track is oval-shaped, or triangular-shaped, or an octogon, as long as the turns are rounded. The reason is that the circumference formula
circumference = 2*PI*r
is true for any arclength.
arclength = (angle in radians)*r
The difference in the radius between lane 1 and lane 2 is the width of the lane regardless of how sharp the turn. So the difference in the arclength between lane 1 and 2 is
arclength difference =(angle in radians)*(width of the lane)
The difference in the length you travel between lanes 1 and 2 depends only on the angle that you're turning through and the width of the lane. It doesn't matter if you turn with a constant radius (a circle), or turn with a constantly changing radius. If you end up turning 360 degrees, or 2*PI radians, the difference between lane 1 and 2 is
2*PI*(width of lane)"
