WebDefinition: A strain gauge is one of the imperative devices used in the field of geotechnical engineering to measure strain on diverse structures. By applying an external force, there … WebThese equations are, Any three gages used together at one location on a stressed object is called a strain rosette. To increase the accuracy of a strain rosette, large angles are used. A common rosette of three gages is where the gages are separated by 45 o, or θ a = 0 o, or θ b = 45 o, or θ c = 90 o. The three equations can then be simplify to.

WebA strain gauge is ‘a sensor whose resistance varies with applied force.’ (2) The variation in length produced by the force causes a change in electrical resistivity across the gauge which can be measured and used to calculate values of stress and strain.
