A truck with 1535 kg mass and center of gravity at point C is used to pull a dumpster with 1700 kg mass and center of gravity at point G. The coefficient of static friction between the tires and pavement is 1.1 and between the dumpster and pavement is 0.5. Assume the truck’s engine has sufficient power and the dumpster does not tip.

Determine whether the truck is able to pull the dumpster if the truck has rear-wheel drive.

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.
