Two previously undeformed rod-shaped specimens of copper are to be plastically deformed by reducing their cross-sectional areas.

One has a circular cross section, and the other has a rectangular cross section. During deformation, the circular cross section is to remain circular, and the rectangular cross section is to remain rectangular. Their original and deformed dimensions are as follows:
Circular (diameter, mm) Rectangular(mm)
Original dimensions 18.0 20 x 50
Deformed dimension 15.9137 x55.1

Required:
Which of these specimens will be the hardest after plastic deformation, and why?

Engineering
