Calculate ΔU, ΔΗ, Q and W for 1 kg of air that undergoes the following mechanically reversible process: Isobaric heating from 300 K and 1bar until the three times the initial volume. Make the assumption that that PV/T=83.14 (bar-cm3 )/(mole-K) and the CP for air is 29 Joule/(mole-K) and the molecular weight of air is 28.9 g/mole.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
