1. A rigid tank contains water vapor at 250°C at an unknown pressure?. The tank is cooled to 150°C when the water vapor starts to condense. Estimate the initial pressure in the tank The final state is saturated vapor.
P1= ___________ MPa
2. (a) volumetric percentage of the propane liquid phase left the cylinder
(b) Mass fraction of liquid propane in the cylinder
(c) What’s the volume of the cylinder excluding propane... Imagine that with propane is a bulk volume and without propane (which is occupying the pore space) you are evaluating the volume of the material. Assume it’s made of iron (density is 491 Ib/ft3)
3. A load of 2 kN is applied to a bracket that is firmly attached to a wall.
Assume the front plate does not bend and all rotation is due to the circular rod.
The rod is composed of a solid steel inner rod and a copper outer casing.
What is the maximum shear stress (either material) in the rod if the two metals are firmly bonded together (no slipping). Assume Gsteel = 80 GPa and Gcopper = 48 GPa.
4. Determine the force in each spring and the deflection of node A. Take F=2.2KN, K1=1KN/CM, K2=2KN/CM, K3=3KN/CM
5. Determine the force in members a, b, and c. Stare whether the members are in tension or compression.
6.
