How can air planes stay in the air when they weigh so much ?? (scare)?

Question

i was day when i whet to a musam aboput air planes

i always wonderd about so pleazzzzzz

i mean one day one air plane might on someone sarce stuff out there

answer quick

Answer 1

Planes stay  aloft because their wings generate enough lift to sustain them in the air. The designed lift generation is far in excess of the maximum planned weight of the aircraft plus fuel plus passengers. Please donot worry, these machines are safe and designed to carry the loads which are put on board.

Answer 2

thrust and lift ratio is far superior compared 2 the weight

Answer 3

Lift is present when a solid object deflects or turns a moving flow of fluid. Flow turns in one direction, while lift is produced in the opposing direction. Solid surfaces of all types are able to cause the flow to turn aside, ensuring that airplanes stay up in the air. For example, both the upper and lower portions of an airplane’s wing surface are important in deflecting the flow of fluid.

Motion is also vital in ensuring that airplanes stay up and don’t come crashing down. Without movement, lift is not generated. Also, there must be a velocity difference between the plane and the fluid. Airplane lift is generated perpendicular to motion. Motion does not act alone when airplanes fly through the sky, however; drag opposes motion, contributing to the science of flight as well.

Besides lift, motion, and drag, weight and thrust are also important in making sure airplanes stay up in the sky. The weight of an airplane is spread out, keeping it balanced. It is this force that pulls a plane toward the ground. Thrust, provided by the airplane’s engines, moves it forward and drag slows it down. Without these forces, each working in its own way, an airplane could not fly.

Answer 4

Yes, some of them are very heavy, but they also produce a great amount of lift.  A fully loaded 747-400 can weigh as much as 900,000 pounds.  But those huge wings produce 980,000 pounds of lift, so it flies.

And it will keep on doing it, too.  The people who designed and built the airplanes know what they are doing.  It will fly, and it won't suddenly fall down, like Wile E. Coyote.  They stay up.

So have a good flight.

Answer 5

The key to this is the shape of the cross-section of the wing. Imagine a horizontal line drawn through the wing shape from front to back. The wing profile is arranged so that the length of the upper part of the profile is longer (i.e.the wing is thicker) than the profile length (and thickness) of the lower part. When the plane moves forward due to the thrust of the engines, the air flows over both upper and lower profiles. But, because the upper profile is longer, the air must speed up as it travels across the wing and this results in a reduction in air pressure above the wing. Therefore the air pressure below the wing is higher than that above the wing and this difference in pressure causes the aircraft to rise. As long as the aircraft is moving forward, this lift force will keep it in the air.

Answer 6

an aircraft has  four forces.thrust,drag,lift,and weight
