This [emphasize] dimensionless quantity is one of the two main quantities measured by the SMARTS (“smarts”) neutron diffractometer. By using a camera to track specific points of a sample, this dimensionless quantity can be measured over a large area using digital image correlation. A device that measures this dimensionless quantity, whose namesake factor depends on the resistivity of alloys like constantan (“constant-tan”), can be used in theories named for this quantity (10[1])being “finite” or (10[1])“infinitesimal.” Increasing this dimensionless quantity leads to an increase in a Wheatstone bridge’s resistance in a common design for their (10[1])namesake (-5[1])gauges. (10[1])The (10[1])negative ratio of two values (10[1])of this quantity, (10[1])respectively measured transversely (10[2])and axially, (10[1]-5[1])is denoted nu and is named for Poisson (“pwah-SAWN”). For 10 points, what ratio of extension (-5[1])to original length (10[1]-5[1])is often plotted alongside (10[2])stress? (10[3])■END■ (10[8])
