Asingle crystal of a metal that has the fcc crystal structure is oriented such that a tensile stress is applied parallel to the [100] direction. if the critical resolved shear stress for this material is 0.8 mpa, calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the [011] direction.

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
