je me souviens a l'IUT on avait eu un sujet du meme style ave un coureur cycliste,un truc avec son rythme cardiaque la longueur de ses foulees ,un truc de fou completement faux vu les approximations et les hypotheses

"on supposera que le rythme cardiaque va varier selon une droite d'equation machin truc muche ,et que le joggeur fait son jogging sur un terrain parfaitement plat,avec des foulees de 78.48951238 cm,il porte un calecon mauve,donc avec un coefficient de sudation plus important qu'un slip jaune"

enfin vous voyez le tableau quoi....

bientot on va nous demander de decrire la forme d'un cul de bouteille avec des courbes de bezier et des courbes parametrees...

XD :lol: :lol: :lol:

Pour les bars, il faut partir du principe que la pression relative est de 1 bar, la pression absolu étant 0 bars, mais la Pa est 1 bars, donc l'hydrostatique nous dit P = H x D le tout / 10, 2 avec H la hauteur, D la densité du liquide, et 10,2 la constante pour avoir des bars, ce serait 10 si on voulait des Kg/cm², a partir de la, le calcul de la P est facile, ce qui l'est moins c'est le fait de reflechir en pourcentage...

A 10 m on a pris 1 bar soit par rapport a la Pa, 100 %
A 20 m on a repris 1 bar mais par rapport au 2 bars initiaux cela ne représente que 50 %, et ainsi de suite .., c'est toute l'importance des paliers entre 10 et 0 mètres !!!!.

Il descend à 40m, donc pression = 5bar. Sa consommation est alors de 20l x 5 = 100 litres/minute.
