This is a subjective question, hence you have to write your answer in the Text-Fleld given below. A metal has a flow curve with strength coefficient =850MPa and strain-hardening exponent =0.30. A tensile specimen of the metal with gage length =100mm is stretched to a length =157mm. Determine the flow stress at the new length and the average flow stress that the metal has been subjected to during the deformation. [3]
