For a typical yarn tensile test, force (F) in Newton and elongation (e) in cm are related as under
F = 2 + 4e + 3e²
. If the yarn fails at an elongation of 3 cm, the work of rupture in N-m, accurate up to first decimal place, is
F = 2 + 4e + 3e²
. If the yarn fails at an elongation of 3 cm, the work of rupture in N-m, accurate up to first decimal place, is
Correct : 0.5
