Nitrogen (N2) gas within a piston–cylinder assembly undergoes a process from p1 = 20 bar, V1 = 0.5 m3 to a state where V2 = 1.75 m3. The relationship between pressure and volume during the process is pV1.35 = constant. For the N2, determine (a) the pressure at state 2, in bar, and (b) the work, in kJ.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
