Airplanes are able to fly by utilizing Bernoulli's principle. The shape of an airplane's wing is called an airfoil, and it serves a very particular purpose: the top surface of the airfoil creates a longer path for air to travel than the bottom surface. This creates lift, going upward. View the picture. Question A: This pressure difference is what generates a lift force. If the airfoil has an area of 400 m^2 what lift force is exerted on the plane? Answer in newtonsQuestion B: The airplane has a mass of 220,000 kg. The lift generated by both of the wings is enough to keep the plane in the air. True or False??? This image depicts a diagram illustrating airflow around an airfoil, which is a critical concept in aerodynamics. The airfoil is shown in cross-section, and its streamlined shape is designed to manage the airflow efficiently.Key elements of the diagram include:1. **Airfoil:** The solid shape in the diagram represents the airfoil. It has a rounded leading edge and a tapered trailing edge, characteristic of common airfoil designs.2. **Streamlines:** These are the lines flowing around the airfoil, indicating the path followed by air particles as they move. The streamlines are denser above the airfoil, suggesting faster airflow, and less dense below, indicating slower airflow.3. **Lift Arrow:** A large upward arrow positioned above the airfoil represents lift, which is the aerodynamic force that acts perpendicular to the oncoming airflow. Lift is crucial for flight, allowing aircraft to rise off the ground.4. **Flow Direction:** Arrows along the streamlines show the direction of the airflow, typically from left to right. This directional flow is essential for understanding how the airfoil manipulates the air to produce lift.This diagram is a foundational representation used in studying how wings and other airfoil shapes generate lift, crucial to the science of flight.
