Transverse Sensitivity ErrorsA calculator for
Three-Element Delta (60-degree) RosettesWith a separate transverse sensitivity for each grid.
Indicated Strains (microstrain),
Transverse Sensitivity* (%),
Poisson's Ratio** (nondimensional),
Actual Strains (microstrain),
* Grids 1 and 3 of planar rosettes commonly have the same transverse sensitivity.
** The Poisson's ratio of the material on which the manufacturer's gage factor was measured (usually 0.285).
