In 1856, Lord Kelvin observed that metallic conductors subjected to mechanical strain exhibit a change in their electrical resistance. Since that time, engineers have attempted to measure and quantify ...

“Gauging the strain,” February’s Special Report on Data Acquisition, presented traditional strain gage theory and highlighted several instruments and bridge amplifiers suitable for use with strain ...

When designing an experiment or test, simplicity is important. Each process added to a test or experiment to obtain data increases the potential for error. For ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...
