Question

Algebra (expressions) The center of gravity of an object is the place where you can lift it and not have it tilt forwards, backwards or sideways. It is important that the center of gravity of an aircraft be in line with the wings, or the aircraft will not fly well. Lift of wings Force of gravity Center of gravity - -Center of gravity Stable flight Unstable flight The position of the center of gravity is found by a special kind of averaging of the positions of the weights of the parts of the airplane. The average is computed by multiplying the weight of each part by its location (as measured from a specific point, such as the back of the airplane), and then dividing by the sum of the weights. For example: 95 ft Positon of center of gravity (as measured froim end of the airplane) 75 ft 10ft =500 x 10 + 2500 x 75 + 800 x 95 500 2500+800 500 lbs 2,500 lbs 800 lbs 500 + 187500 + 76000 3800 70.65 feet (ansver in same units as the positions) Determine the position of the center of gravity of this design for a flying pterodactyl. (Use the simplified weight diagram to do so.) Do you think it will fly stably? 45 inches 16 inches 15 lbs 4 lbs Wings attached Design of Pterodactyl Weight diagram Give answer to one decimal place. Example 12.3

Center of gravity position?

Will the flight be stable?

Answer 1

Thanks

2 s2hs point Prgtt ill be unstable because centre
