Why might there be multiple foremen on one work site? 1. There is a shortage of workers and foremen are responsible for filling in the gaps. 2. There are multiple construction managers who need to be supervised.
3.Construction crews work best when the number of foremen equals the number of workers.
4. The project involves multiple trades with different crews specializing in each trade.

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.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
