Statement for Linked Answer Questions 54 and 55:

The strain hardening behaviour of an annealed rod during cold rolling is given by  \bar \sigma = 700\ (\epsilon)^{0.2} MPa, where  \bar \sigma is the flow stress at strain  \epsilon .

F low stress after 50% reduction in area of the annealed rod on cold rolling is approximately

  1. 609 MPa
  2. 750 MPa
  3. 559 MPa
