In order to properly ascertain the response of an arbitrary body (Fig. 2.1), one needs to do very controlled measurements (Fig. 2.2). For illustration purposes consider the measurement of the displacement ( \(u+\varDelta u\) ) of point B, the displacement of point A of the sample (u) and the difference between them, divided by the original length ( \(\varDelta x\) )

In order to properly ascertain the response of an arbitrary body (Fig. 2.1), one needs to do very controlled measurements (Fig. 2.2). For illustration purposes consider the measurement of the displacement ( \(u+\varDelta u\) ) of point B, the displacement of point A of the sample (u) and the difference between them, divided by the original length ( \(\varDelta x\) )
