Slide 3

Before each experiment is run the sample must be measured. Using dial calipers we first measure the gauge section inner and outer diameter. To determine gauge length we first locate the positions at each end of the sample where the diameter is 4% greater than the gauge diameter. These positions are marked and are taken to define the gauge section. Once marked, the distance between the marks is measured to give the gauge length. The choice of fixing the gauge length at a position where the diameter has increased by 4% is somewhat arbitrary – we could have chosen 1% or any other small fraction.
