The main purpose of a strain gauge is to indirectly determine stress and its variation with time, quantitatively.
Every component in a linear motion system experiences some form of loading due to applied forces or motion. Strain is the deformation or displacement of material that results from an applied stress. The most common way to analyze the relationship between stress and strain for a particular material is with a stress-strain diagram. For many materials, the proportional limit and the elastic limit are the same or nearly equal. In the stress-strain curve shown here, the proportional limit and the elastic limit are assumed to be the same.

Bench mounted bending system to test tension, torsion and bending to illustrate how resistance strain gauges work and methods of measuring strains in different structures. Can be used to demonstrate Young's modulus and Poisson's ratio. The compact Strain Gauge Trainer fits on a bench or desktop. It contains everything needed to show students how resistance strain gauges work on three different structures. It is ideal for groups of two or more students to do experiments and for classroom demonstrations.
STRAIN GAUGE TRAINER
A strain gauge also spelled strain gage is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in , the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern.
The backing material performs Bonded Strain Gauges These gauges are directly bonded that is pasted on the surface of the structure under study. From the measured electrical resistance of the strain gauge, the amount of applied stress may be inferred. In this picture, the crack can be seen to have widened by approximately 0. What are strain gauges and what types of strain gauges exist? The Model EDSV strainmeter is suitable for embedment in soil or concrete or for surface mounting by welding on steel structures.
Strain gauges may be used in "smart bridge" technology to detect structural problems early. Strain gauge technology has practically unlimited uses in the field. It can be used to test vehicles, ship hulls, dams, and oil drilling platforms.
