The smooth disks d and e have a weight of 200 lb and 100 lb, respecively. if a horizontal force of p=200 lb is applied to the center of disk e, determine the normal forces at the points of contact between the disks and between the disks and the ground

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
