In a special torsion pendulum used for elastic after?effect measurements, it is not practical to measure the relaxation time if it is less than 1 minute. On this basis, determine the maximum temperature at which the apparatus should be used for determining the relaxation time of nitrogen atoms in iron. Take ? ? 0.28664 ?? and see Table 13.2 for the diffusion equation of iron.
