Two previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. one has a circular cross section, and the other is rectangular; during deformation the circular cross section is to remain circular, and the rectangular is to remain as such. their original and deformed dimensions are as follows. which of these specimens will be harder after plastic deformation? circular (diameter, mm) rectangular (mm) original dimensions 15.2 125 × 175 deformed dimensions 11.4 75 × 200

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
