Design a quick return four bar mechanism that will have time ratio of tr 1: 1.25 . the output link should scan 60° angle for a full crank rotation . the length of output link is 5.0 em 1)-find the length of the other links and draw the mechanism .(write down your steps) 2)-does the mechanism satisfy the grashof's condition. 3)-find the max and min transmission angles over the range of motion using graphical technique

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
