The empirical relation determined for the real tensile diagram of a rigid, linear hardening material with yield limit 0 is given as = 0 + . In addition, although the region where the sample necks cannot be seen in the real tensile diagram, it is known that the sample necks when the loading is maximum. Accordingly, calculate the actual strain ( ) value and the unit strain () value at the moment when the material characteristic = 0 + 300 is
