The tensile testing is carried out by applying longitudinal or axial load at a specific extension rate to a standard tensile specimen with known dimensions (gauge length and cross sectional area. This process is controlled by eEF1 which catalyzes the delivery of aa- tRNA (1) to the site of elongation. Elongation index is more than 15% then the aggregate is undesirable for any construction work. << Length/Elongation Index Gauge Aggregate sample to be tested FLAKY A flaky particle is the one whose least dimension (thickness) is than 0.6 times the mean size. /BitsPerComponent 8 PDF Flakiness and Elongation Index of Aggregate /SMask /None>> (PDF) LABORATORY EXPERIMENTS TENSILE TESTING - ResearchGate Weigh the elongated material passing through the specified gauge from each fraction e 1 +e 2 +e 3 +e 4 +e 5+=E. Mutations could also affect, The lab focuses on three types of eEFs; eEF1, eEF2 and eEF3 with most focus on the eEF1 which is the prototype of G- proteins. In addition, the percentage of flaky or elongated particles in an aggregate sample can be determined and discarded. Uniaxial tensile test is known as a basic and universal engineering test to achieve material parameters such as ultimate tensile strength (UTS), yield strength (YS), % elongation, % area of reduction and young's modulus. Each fraction is gauged in turn for thickness on the metal gauge. Apparatus required for elongation index determination tests are: 1.
