Challenge Problems
Push your limits with challenges.
Question 1
If a bird's wing has an area of 20m² and generates lift at a speed of 15m/s, while the air density is 1.2 kg/m³, calculate the lift coefficient if the total lift generated is 12,000 N.
💡 Hint: Remember to reorganize the lift equation to isolate for CL.
Question 2
Discuss how the principles learned from bird flight could be applied to improve drone technology.
💡 Hint: Think about how size and wing shape affect performance in both birds and drones.
