A strain gauge (sometimes gage) is a device used to measure physical force. Strain gauges are often used in mechanical engineering research and development to measure how much stress a machine produces. Most are no more than an inch across. Strain gauges are used in aircraft component testing and other manufacturing applications. The majority use very thin wire, though other types exist. A bonded gauge is a strain gauge glued to a test specimen. The gauge itself can be of use only when the... więcej
