PRACTICAL STRAIN GAGE MEASUREMENTS - OMEGA

we typically measure with a bonded resistance strain gage. Strain may be either tensile (positive) or compressive (negative). See Figure 2. When this is written in equation form, = L/L, we can see that strain is a ratio and, therefore, dimensionless. To maintain the physical significance of strain, it is often written in units of inches/inch. For most metals, the strains measured in ...
