Stress-Strain Measurement and Strain Gauge - DAV University
www.davuniversity.orgo Strain gauges given indication of strain at only one point. o Strain gauges are mostly used to measure strains on the free surface of a body. The state of strain at any point on the free surface of a body can be characterized in terms of three Cartesian strain components xx, yy and xy as

Fortunately, there are circuits available to do just that.
Strain Gages - Pennsylvania State University
www.me.psu.eduStress, Strain, and Strain Gages, Page 2 Strain gage The principle discussed above, namely that a wire’s resistance increases with strain, is key to understanding how a strain gage works. The strain gage was invented by Ed Simmons at Caltech in 1936. A strain gage consists of a small diameter wire (actually an etched metal foil) that is attached to a backing material …
