A steel wire of length $$100$$ $$m$$ and diameter $$12.214$$ $$mm$$ is drawn to a final diameter of $$10mm.$$ Tensile tests of specimen made before and after the drawing operation gave yield stress as $$200$$ $$MPa$$ and $$400$$ $$MPa$$ respectively,

The length of drawn wire is

A steel wire of length $$100$$ $$m$$ and diameter $$12.214$$ $$mm$$ is drawn to a final diameter of $$10mm.$$ Tensile tests of specimen made before and after the drawing operation gave yield stress as $$200$$ $$MPa$$ and $$400$$ $$MPa$$ respectively,

The yield stress of the steel at a true stain $$0.2,$$ by assuming linear strain hardening law.
