Abstract
Cet instrument comprend essentiellement deux pièces coudées 11, 12 portant des touches constituées par des pointes et un ressort de flexion 13. En utilisation, les pointes sont appliquées sur l'éprouvette 25 dont il s'agit de mesurer l'allongement par des ressorts 26 et 27. Le ressort de flexion 13 porte une jauge d'allongement ou de contrainte électrique ou de préférence deux jauges respectivement sur ses deux faces. Des pièces coudées supplémentaires 21 et 22 serrées sur l'autre face du ressort 13 servent à limiter le mouvement possible des pièces il, 12 et la flexion possible du ressort 13.
