Comme on peut le voir sur la figure, la force de tra\u00een\u00e9e provient de la diff\u00e9rence entre les pressions qui s’exercent \u00e0 l’avant et \u00e0 l’arri\u00e8re du corps immerg\u00e9.\u00a0Pour cette force peut \u00eatre calcul\u00e9 (dans ce cas) en utilisant simplement la d\u00e9finition de la pression comme:<\/p>\n
