A vertical piston-cylinder that initially has a volume of 0.2m^3 is filled with 0.2kg of air. The piston is weighed so that the pressure on the air is always maintained @ 2 bars. Heat transfer is allowed to take place until the volume is 75% of its initial value.
Determine A) the initial and final temperature of the air in K. and B) the quantity and direction of the heat transfer in KJ. Air is modeled as an ideal gas.
It supports a vertical axial compressive load of 7000 lb on top and a horizontal load of 1000 lb at a point 3 ft below the top. Compute the maximum and minimum combined stre
