causes drag. Drag can be measured by the equation D=Cd 1/2 (pV2)S‚ much like the lift equation. The drag coeficent Cd is found‚ again‚ by determining the shape of the airfoil and then finding the angle of attack. Drag is less than lift up to a certain angle of attack. After that‚ the air encountering the surface of the wing is either pushed off or deflected in a way to cause turbulance. So‚ what does lift and drag have to do with airflow? As hinted in the above paragraph lift and drag are

years with sailboats and windmills.[1] Images and stories of flight have appeared throughout recorded history‚[2] such as the legendary story of Icarus and Daedalus.[3] Although observations of some aerodynamic effects such as wind resistance (e.g. drag) were recorded by Aristotle‚ Leonardo da Vinci and Galileo Galilei‚ very little effort was made to develop a rigorous quantitative theory of air flow prior to the 17th century. In 1505‚ Leonardo da Vinci wrote the Codex on the Flight of Birds‚ one

the force of gravity will cause it to speed up as it falls. But friction with the air‚ called drag‚ will tend to cause it to slow down. How much drag there is depends mostly on two factors: speed and shape. The faster an object moves through air the more drag there is. A compact object experiences less drag than an object of the same mass that is spread out. As a falling object speeds up‚ drag increases until it is equal to gravity. At that point‚ the object continues to fall at a constant

What is the relationship of lift‚ drag‚ thrust‚ and weight when the airplane is in straight-and-level flight? Lift equals weight and thrust equals drag. During the transition from straight-and-level flight to a climb‚ the angle of attack is increased and lift is momentarily increased. During a steady climb‚ the angle of climb depends on excess thrust. A propeller rotating clockwise‚ as seen from the rear‚ creates a spiraling slipstream that tends to rotate the aircraft to

competitions such as swimming and athletics‚ drag and lift forces are constantly responding to the object or body’s thrust. There are many types of forces exerted by fluids that resist an implement or body trying to move through it. At the same time‚ technological improve- ments have enabled us to better use the specific fluid to decrease resistance; for example‚ better configuration of the dimples on a golf ball can improve its flight performance. Drag is the force that opposes the forward motion

today. Lift‚ weight‚ thrust‚ and drag. During flight‚ there is a constant relationship between these forces. Lift is the upward force created by the effect of airflow as it passes over and under the wing. The airplane is supported in flight by lift. Weight‚ which opposes lift‚ is caused by the downward pull of gravity. Thrust is the forward force which propels the airplane through the air‚ which varies with the amount of engine power being used. Opposing thrust is drag‚ which is a backward‚ or retarding
