Afighter pilot dives his plane toward the ground at 230
m/s. he pulls out of the dive on a vertical circle. what is the
minimunradius of the circle, so that the normal force exerted on
the pilotby his seat never exceeds three times his weight?

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
