Is prandtl lifting line theory predicts lift distribution over a three dimensional wing?

Correct Answer: True
The prandtl lifting-line theory is a mathematical model that predicts lift distribution over a three dimensional wing based on its geometry. It is also known as the lanchester-prandtl wing theory. The theory was expressed independently by Frederick w. lanchester in 1907.

Is prandtl lifting line theory is a mathematical model that predicts lift distribution over a three-dimensional wing?

According to the reasoning given by Prandtl for his lifting line theory, finite wing is like a ________

The downwash along the wing in the downward direction in Prandtl’s lifting line theory comes from______

Simplify : $${{{5 \over 3} \times {7 \over {51}}{\text{ of }}{{17} \over 5} - {1 \over 3}} \over {{2 \over 9} \times {5 \over 7}{\text{ of }}{{28} \over 5} - {2 \over 3}}}$$

An aircraft with elliptic wing planform has parasite drag coefficient as 0.6. Lift coefficient of wing is 0.25 and aspect ratio is 7.5. If induced drag co-efficient is 0.0235 then, find total drag coefficient for the wing.

An aircraft with elliptic wing planform has parasite drag coefficient as 0.9. Lift coefficient of wing is 1.8 and aspect ratio is 8.5. Find total drag coefficient for the wing.

In a weight-lifting competition, the total weight of Joe's two lifts was 750 pounds. Twice the weight of his first lift was 300 pounds more than the weight of his second lift. What was the weight, in pounds, of his first lift?

In a weight -lifting competion, the total weight of Jabir's two lifts was 750 pounds. Twice the weight of this lift was 300 pounds more than the weight of his secnd lift. What was the weight , in pounds, of his first lift?

A twin turboprop engine is flying with 120m/s. Wing of the aircraft has span of 2m and lift co-efficient as 0.15 with aspect ratio as 9.2. Find the lift produced by the wing.

A subsonic aircraft has unswept wing which has maximum lift coefficient of 1.4. Now, consider wing is provided sweep of 25° at quarter chord point. Now, determine the change in maximum lift coefficient due to the provision of sweep.
