Abstract
THIS is a very useful and ingenious apparatus for measuring the extension or compression produced on any material by tensile or compressive forces. Such deformations having been observed, the corresponding variation in the stresses to which the material has been subjected may at once be inferred by the ordinary law of elasticity connecting strains and stresses in solid bodies. The instrument affords one of the many examples of the valuable results obtainable by the simplest possible mechanical means—results which before the construction of the strain-indicator were considered altogether unattainable.
