A strain gauge is a device used to measure the strain or deformation of an object. It consists of a thin wire or foil that is attached to the object being measured. As the object deforms under stress, the resistance of the wire changes, allowing the strain gauge to measure the amount of strain. Strain gauges are commonly used in engineering and materials testing to monitor the structural integrity and performance of various components. **
