Strain Gauge

A strain gauge is a device used to measure how much an object deforms or stretches under stress. When attached to a material, it detects tiny changes in length caused by forces like pressure, weight, or tension. These small changes alter an electrical property within the gauge, typically its resistance. By measuring this change, engineers can determine the amount of strain or deformation in the material. Strain gauges are widely used in testing structures, machinery, and materials to ensure safety and performance, providing precise data on how objects respond to various forces.
