Ashaft is loaded in bending and torsion such that the bending moment at a critical cross section varies between 125 n. m and –15 n. m, and torsional moment varies between 80 n. m and –10 n. m. the shaft is made of steel of ultimate strength 700 mpa, yield strength of 400 mpa and a fully corrected endurance limit of 210 mpa can be assumed. the cross section is part of a stress concentration feature where kt = 2.2 and kts = 1.8. find the minimum acceptable diameter using de-goodman criterion for a safety factor of 2.0. also calculate the first cycle yielding safety factor.

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.
