How do these movable sections affect the lift force?
As we flew across the Pacific, I spent a lot of time looking out across the wing at the cloudscape below. Dozens of questions came to mind about the formation of clouds, their shape, why they form in layers, etc., but what made me slightly nervous was the amount of upward force that must be exerted on the wings to allow us to remain in equilibrium up there. Apparently the mass of a fully loaded 777 is about 300,000 kg.
So the physics question for this day/night(?) is: The lift force on this 300,000 kg plane must be about 3,000,000 N. What are the factors that affect his lift force?
