Agas undergoes a cycle in a piston–cylinder assembly consisting of the following three processes: process 1–2: constant pressure, p = 1.4 bar, v1 = 0.028 m3, w12 = 15 kj process 2–3: compression with pv = constant, u3 = u2 process 3–1: constant volume, u1 - u3 = -25 kj there are no significant changes in kinetic or potential energy. (a) calculate the net work for the cycle, in kj. (b) calculate the heat transfer for process 1–2, in kj.

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
