The counterweight is a captured asteroid with a 1km radius and a mass of 8.37758 x 1012 kg. The design altitude is taken to be h = 36,063.9 km. What factor would the current yield stress of carbon nanotubes have to be multiplied by to achieve such a configuration?

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
