A wire of length L 5 4 ft and diameter d=0.125 in. is stretched by tensile forces P= 600 lb. The wire is made of a copper alloy having a stressstrain relationship that may be described mathematically by:. sigma = 18000 epsilon/1 + 300 A) Determine the stress on the wire due to the force P=1.B) Determine the strain, epsilon_p, in the wire due to the force epsilon P= 3pt . C) Determine the elongation. delta_L, of the wire in inch due to the force P delta_L= 1ptD) Determine the residual strain, epsilon_R, if the force P is removed, epsilon_R= 3pt. E) Determine the permanent set (or elongation) of the wire, delta_permanent= 2pt. F) What is the elastic strain recovery, epsilon_Recovery= 2pt. G) What length of wire was elastically recovered, delta_Elastic= 2pt. H) If the force is applied again, what is the proportional limit, on sigma_PL= 2pt. I) What is the toughness of the original wire assuming it breaks at a strain of 0.03. toughness= 4pt.

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.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
