Strain gauges are used in force measuring transducers and sensors in aircraft and missile production, mechanical engineering, railroad car manufacturing and other industries. May 04, 2010 · It depends on the type of rosette, and the state of strain you expect. If you use a two-element 90 degree rosette and you want to measure shear strain, the orientation does matter. For example if you put the gauges along the axis and round the circumference of a shaft with a torsional stress, both gauges will read a direct stress of zero.
