An airplane is in trimmed flight and has a weight of 4500 lb. the distance between the aerodynamic center of the wing to the aerodynamic center of the tail is 20 ft. assume that there is no pitching moment at the aerodynamic center of the wing or at the aerodynamic center of the tail. also, neglect any drag influence on the pitching moment of the aircraft.1. calculate the location of the center of gravity of the trimmed aircraft when the wing produces 90% of the needed lift and the tail produces 10% of the needed lift. measure the location of the center of gravity as a distance aft of the wing aerodynamic center

answer:

all three have their own beauties

explanation:

it is difficult to choose someone as most beautiful

it depends where you live and what they have said for that place.

Explanation:

A Carnot heat engine receives heat from a reservoir at 900$^\circ{}$C at a rate of 800 kJ/min and rejects the waste heat to the ambient air at 27$^\circ{}$C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5$^\circ{}$C and transfers it to the same ambient air at 27$^\circ{}$C. Determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air. Answers: (a) 4982 kJ/min, (b) 5782 kJ/min
