What are the things on top of a plane called to lift the plane?
airfoils
What angle does a plane lift off?
15 degrees
How do winglets on a plane help the plane?
Winglets descrease induced drag (drag from the production of lift) created by wing-tip vortices, simply turbulent airflow off the edge of the wing. So they do increase handling characteristics and fuel efficiency because of the increase in lift and decrease in drag. Hope this helped!
What keeps an air plane up in the air?
An airplane stays up in the air due to a combination of factors. The main factor is the shape of the wings, which creates lift as air flows over and under them. The engines also provide thrust to move the plane forward, and the overall design of the plane helps maintain stability and control during flight.
How can an inclined plane help you safely lower a heavy object?
Inclined plane are just fancy words for a ramp. By using an inclined plane you could slide the heavy object down it or you could carry it down it instead of having to use steps or lift it from a decent height, thus lowering the risk of injury.
