EngineeringA2Z Circuit Diagram A strain gauge (or, less commonly, strain gage) is a widely used sensor tool for measuring stress forces in an object or material under load. By showing how strain and fatigue forces are impacting a physical material, strain gauges enable engineers to make various key decisions about all kinds of designs, builds and installations.
measure the strain on individual members of a structure or machine. Then we use the stress-strain relationships to compute the stresses in those members to verify that these stresses remain within the allowable limits for the particular materials used. STRAIN When a force is applied to a body, the body deforms. In the general case, this The measure of resistance determines the strain applied. Measurement of Strain Using Strain Gauge : The strain gauge can be used in different possible arrangements for measuring strain. They are, In this first arrangement, a single strain gauge SG 1 is fixed on the elastic member (which is under test) as shown below. Here the strain gauge

Stress is a measurement of the force applied divided by the initial cross-sectional area of an object, or the internal resisting capacity of an object. Figure 1. Left: Composition of a strain gauge Torque vs. Time testing measurements using a strain gauge. Conclusion. By using two strain gauges in the bridge, the effect of temperature can be avoided. For example, Figure 5 illustrates a strain gauge configuration where one gauge is active (R G + โR), and a second gauge is placed transverse to the applied strain. Therefore, the strain has little effect on the second gauge, called the dummy gauge.

Key learnings: Strain Gauge Definition: A strain gauge is a device that measures the deformation (strain) of an object when force is applied, through changes in electrical resistance.; Working Principle: The strain gauge detects minute geometrical changes as resistance changes, which indicate the level of stress on the material.; Bridge Circuit: The strain gauge is part of a bridge circuit
