on what principle does aeroplane works
Answers
Answer:
see the given attachment
Explanation:
Aeroplane can fly in air due to mainly four aerodynamic forces. Namely weight, lift, drag, thrust these are four aerodynamic forces. Weight is due to earths gravitational attraction, lift is a force which is in vertically upward direction of aircraft. Lift produced in aircraft is due to wings. Lift on the aircraft can be controlled by controlling angle of attack (inclination of aircraft with respect to ground) & speed of aircraft. Lift depends upon suraface area of wing. Hence at the time of take off & landing flaps are used to increase surface are. Drag is a force which is resistance to the motion of aircraft. Drag force is used to reduce the speed of aircraft at the time of take off & landing. Sopilers are used to increase drag. For more information about
