The uniform panel door weighs 60 lb and is pre-vented from opening by the strut C, which is a light two-force member whose upper end is secured under the door knob and whose lower end is attached to a rubber cup which does not slip on the floor. Of the door hinges A and B, only B can support force in the vertical z-direction. Calculate the compression C in the strut and the horizontal components of the forces supported by hinges A and B when a horizontal force P = 50 lb is applied normal to the plane of the door as shown.
Ten cubic feet of air is cooled at a constant pressure of 80 psi. The initial temperature is 180 0F and the final temperature is 100 0F. Assume air is an ideal gas, Cp = 0.241 Btu/lb 0R and Cv = 0.173 Btu/lb 0R and R = 1545 lbf/lbmol 0R, M = 28.97 lb..

air enters the compressor of a regenerative gas-turbine engine at 300k and 100 kpa where it is compressed to 800 kpa
A diesel engine has a temperature of 540R and a pressure of 30 psi at the beginning of compression. After the heat addition process the temperature is 2600R and the pressure is 1000 psi.
Consider a sealed can that is filled with refrigerant-134a at 20°C. Now a leak develops, and the pressure in the can drops to the local atmospheric pressure of 80 kPa. What is the temperature of the refrigerant in the can when the pressure drop is co..
