Excerpt from Des Ponts en Fil de Fer Un autre obstacle ??? l'entploidcs fers de gmeoedimensious est la difficult??? de s'assurer de leur force, et l'incertitude o??? l'on est toujours de savoir si dans l'essai on n'a pas pouss??? la charge au point d' alt???rer la barre. On sait en effet, qu'entre les d???fauts cach???s qui peuvent exister dans l'int???rieur d'une barre un ouvrier, quel que exerc??? qu'il soit, n'est jamais parfaitement s???r de faire une soudure qui r???u nisse compl???tement les deux sections du fer. Il pourra donc arriver que l'essai qui en sera fait se trouve imm???diatement au - dcssous de la limite de la t???nacit??? de la barre dans cette partie, et lui fasse ???prouver une alt???ration qui la rende incapable de r???sister ensuite ??? des efforts beaucoup moindres supposons, en effet, que l'on essaie une chaine de too m???tres compos???s de so cha???nons et qu'eula sou mettant comme ont fait les Anglais Mme ???preuve de 13 kil. Par millim???tre carr???, un des anneaux vienne ??? rompre, il y aura une assez grande probabilit??? de croire qu'il se trouve dans la chaine des anneaux qui auraient rompu sous 17 kil. Enfin ??? une limite aussi rapproch???e que l'on voudra du nombre ci-dcssus. Il sera donc de la plus s???v???re prudence de ne calculer la force absolue de la chaine en d???rc que sur 16 kil., et de ne le charger que d'un poids dont onpr???sumeque le renbuveemmt trop fr???quent ou la continuit??? ne puisse l'alt???rer.
