7.32 experimentally, it has been observed for single crystals of a number of metals that the critical resolved shear stress τcrss is a function of the dislocation density rhod aswhere τ0 and a are constants. for copper, the critical resolved shear stress is 2.10 mpa (305 psi) at a dislocation density of 105 mm-2. if it is known that the value of a for copper is 6.35 10-3 mpa-mm (0.92 psi-mm), compute the crss at a dislocation density of 107 mm-2.
The main difference between gui and cli is that the graphical user interface (gui) allows the user to interact with the system using graphical elements such as windows, icons, menus while the command line interface (cli) allows the user to interact with the system using commands
you forgot the rest of the question sorry
my day was okay, a little bit boring. how was yours?
make you upset

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
