Pour trancher cette question, il nous faut simplement refaire le même calcul que ci-dessus, mais pour le premier des cas spéciaux étudiés plus haut. Les conditions des deux compensations sont ici les formules (5): /2 â a 2 _a) â(/) d(l Nous posons, exactement comme ci-dessus, l = i, N = l, d'où D = l. Alors : De plus, si nous plaçons le niveau du mercure au milieu / 1 du pendule, nous aurons d = -~ = â . Nous aboutissons ainsi au système des quatre équations suivantes: m I X (X â 1 ) Hâ £ ou bien ou bien OF^ â\ ^ L Pour résoudre ce système, on procède de même que dans le cas précédent. La troisième équation nous donne la valeur de m, en fonction de X : a
