Webanother way to express strain is as percent strain, which is x 100. For example: 0.005 inch/inch = 5000 =0.5%. As described to this point, strain is fractional change in length and is directly measurable. Strain of this type is also often referred to as normal strain. SHEARING STRAIN Another type of strain, called SHEARING STRAIN, is a measure WebAnother important reason for using rosette pairs of strain gauges is compensation for temperature effects. The amplifier is really using the ratio of resistance changes; to the extent that self heating or other common temperature effects change both resistances, a ratio of the changes will remain constant.
