The definition of an airplane according to Marks Standard Handbook for Mechanical Engineers is a mechanically driven fixed-wing aircraft heavier than air which is supported by the dynamic reaction of the air against the wings For an airplane to fly it has three basic concepts One for the airplane to be dynamically shaped for maximum efficiency Two for the airplane to have the power to fly the engines Three for the wings are dynamically shaped in every way so the airplane can have its maximum lift For the wings to have its lift and for it to have its maximum efficiency there are three major concepts for the wings The first concept of the wings is how the wings help the airplane fly The definition of lift according to Marks Standard Handbook for Mechanical Engineers is the component of the resultant force exerted by a fluid on a body perpendicular to the relative motion of the fluid The formula for lift in pounds is CLPAV22 Lift is made by a drop in air pressure creates lift over an airplanes wing An airplane wing has a curved upper surface As a plane moves forward the pressure of that air that rushes over this curved surface falls A high-pressure area always moves toward the low-pressure area The high-pressure area below the wing thus rises toward the low-pressure area above it and so lifts the plane into the air Also having the wing in that shape increases the velocity over the top of the wing relative to the bottom So the velocity goes up and the pressure will go down Which means the lift of the airplane will happen quicker The angle of an airplane wing also has a great affect on its lift The air would go over the top of the wing and will stay there longer because of the different angle of the wing When that happens it also creates more of a lift
