The sector rotates with = 8 rad/s and = 16 rad/s2 about a fixed axis through point B. Simultaneously, the particle A moves in the curved slot with constant speed u = 4 m/s relative to the sector. Determine the absolute velocity and acceleration of particle A, and identify the Coriolis acceleration. The distances r1 = 855 mm and r2 = 305 mm.

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
