A500-mm simply supported square aluminum panel of 20-mm thickness is under uniform pressure po. for e=70 gpa, , and and taking into account only the first term of the series solution, calculate the limiting value of po that can be applied to the plate without causing yielding and the maximum deflection w that would be produced when po reaches its limiting value.

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
