mojito Posted February 5, 2021 Share Posted February 5, 2021 @PassOuPACES, là le schéma n'est pas du tout représentatif, ils ont du prendre des valeurs quelconques sans adapter le schéma Il y a 2 heures, PassOuPACES a dit : f1' qui vaut 3cm, ca veut dire que OF'1 = 3 cm exact Quote Link to comment Share on other sites More sharing options...
