Q. The true stress (in MPa) versus true strain relationship for a metal is given by
σ = 1020e 0.4
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 time of necking (in mm2) is ________________(correct to two decimal places)
