A medium drive of a steel hub of a gear with an outside diameter of 80 mm on a steel shaft is required. a) Make the dimensional decisions for a 49-mm basic size with a medium drive fit for the hub and shaft, and specify dimensions with tolerances for the shaft and the hub bore for the fit. b) When the interference pressure “p” is at a minimum (p at δmin) for the specified tolerances how much torque (in Nm) can be transferred with the medium drive fitted assembly if the steel to steel friction is 0,8 and the hub of the length is 170 mm. E=207 GPa

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.
