Acenter-cracked panel with an initial crack length of 0.010 mm is subjected to a tensile cyclic stress between 25 and 125 mpa for 35 cycles. the panel is then subjected to a tensile cycle stress between 0 and 250 mpa. how many of the larger stress amplitude cycles can be sustained before failure? the material has a fracture toughness of 25 mpa√m and material constants n = 3.1 and c = 1.8 x 10-10 for these units.

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.
