The true stress (in MPa) versus true strain relationship for a metal is given by O = 1020 e0.4 The cross-sectional area at the start of a test (when the stress and strain values are equal to zero) is 100 mm2. The cross-sectional area at the (correct to time of necking (in mm2) is two decimal places).
