The space shuttle is an example of an extremely complicated system using leading edge technology. Give three examples of shuttle components that you think represented unproven technology at the time of its development, and which must have required extensive prototyping and testing to reduce operational risks to an acceptable level.

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
