Auniform steel rod of diameter 7.5 mm is to be manufactured by a stretching process. the original diameter of the steel rod is 12.8mm. the true stress-true stain behavior of the steel is given by attmp13835. (a) is it possible to achieve the desired reduction in diameter uniformly throughout the rod length? show relevant calculations in support of your answer and (b) calculate the work done in stretching the rod till the onset of inhomogeneous (non-uniform) deformation. assume the initial length of the rod to be 50.8 mm.(reading chapter 2.12)
