Acenter-cracked plate is loaded in tension and has dimensions of b = 40 mm, t = 5 mm, and large h, and it contains an initial crack of length 2ai = 8 mm. a zero-to-maximum cyclic load of 80 kn is applied, and the material has σy= 320 mpa, kic= 40 mpa√m.
(a)what is the crack length for plastic yielding, ay?
(b)what is the crack length for brittle fracture, ac?
(c) will the plate fail by
i. plastic yielding before fatigue crack growth,
ii. plastic yielding after fatigue crack growth,
iii. brittle fracture before fatigue crack growth, or
iv. brittle fracture after fatigue crack growth?
briefly explain why.

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.
