What has more lift - the wing of a slow-flying bird or the wing of a fast-flying bird?
Slow flying birds
How does a bird's wings work?
the shape of the wing is airfoil. basically this is what helps it go smoothly through air...http://amasci.com/wing/airfoil.html
How do wings of insects differ from wings of birds?
Windows of insects differ from the wings of birds in that they have no features. They use a thin membrane to catch the wind.the wings of a bird are made out of feathers and creates a shaped across its length like the wing of an airplane, a cross section of the wing, is seen to cause lift from aerodynamics of their shape described above. Since the air creates lift when it has to go faster over the top of the wing than the bottom; this phenomenon of air going at different speeds, cause the lift in the wings of a bird wing. (Or as seen in an airplane wing) Also, birds create jumps in their flying ability when they push their wings down with muscular thrusts while fullly opened, and pick their wings back up high with a light, but quick, easy but with a punctual rhythm of wing lifting that coincides with perfectly with downward flaps, which cause lift and initial velocity/height. Birds have amazingly strong control over how they fly, much more than insects.Insect wings are made out of rigid cells but are delicate if damaged. They rely on fast flapping to create lift, they don't glide as much using open wings like birds. For insects, if they are flying, they are nearly always flapping their wings, and usually with quite a speed of frequency that is much faster than birds.The wings of insects consist of simple membranes of chitin. Bird wings are bone-and-muscle limbs covered in feathers. With the exception of flies, insects have four wings. Birds have two.Bird and butterfly wings have tremendous differences, a bird's wings are made of bone, skin, and feathers whereas a butterflies wings are made of membranes stretched between hollow tubes that protrude from the butterflies body. Instead of feathers, butterflies have colored scales covering their wings. Also a birds wings are an adaptation of their front legs with leaves them with two legs for walking and two wings, a butterfly has six legs for walking and two wings which are not an adaptation of their legs.
Are wax wing birds rare?
No. Both the cedar and bohemian waxwings are common birds.
How do wings fly?
because they flap and collect wind then they get to fly.answer #2a bird wing creates lift by bending and flexing and creating lift by shaping the wing so the air moves over the top faster than the bottom which lowers the pressure on the top and hence "lift". An airplane does the same thing but doesn't flex the wing as a bird does. They do change the shape using flaps and slats and changing the attack angle to the wind as in supersonic aircraft.
What does the difference in air presssure above and below a birds wing cause?
The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
What has more lift - the wing of a slow-flying bird or the wing of a fast-flying bird?
Slow flying birds
What does the increased pressure below an airplane's wing cause?
Lift.
What does the term angle of attack in birds mean?
It is simply the angle that the wing of the bird is to the incoming air force. This term is used when the birds are gliding or not flapping their wings. A change in this angle can cause the bird to be either more streamlined, cause lift, drag or even descent.
How is lift generated in a birds wing?
When in flight, birds flap their wings to push air beneath them. By pushing the air down, they are propelling themselves upwards.
How does thehow is a birds flight and airplanes flight alike and different?
The airplane and bird both generate lift by the air flowing over their wings. The shape of the wings cause a low pressure zone above the wing and a high pressure zone under the wing generating lift. The main difference is the airplane's wings are stationary requiring engines to supply the forward motion to generate the airflow/lift needed. A bird has to flap their wings to generate the forward motion/lift. A bird can cause lift by flapping it's wing up/down but also by changing the angle of it's wings (angle of attack) to generate lift. The bird can generate more forward thrust by also drawing the wings rearward, Different birds fly differently (hummingbirds vs. condors, etc).
When the flap at the rear of an airplane wing is in the downward position the curvature of the wing increases How will this help affect the amount of lift on the wing?
When the curvature of the wing increases, air moving across the top of the wing moves more rapidly. The increased difference in speed between the air above the wing and the air below the wing will help to cause an increased lift on the wing.
2. What are three major factors that can change the velocity and pressure of air flow around a wing and thus increase the amount of lift?
Angle of attack: Increasing the angle of attack of the wing can increase lift by creating more lift-producing airflow over the wing. Airspeed: Higher airspeed results in increased flow velocity over the wing, generating more lift. Aircraft weight: Lighter aircraft require less lift, while heavier aircraft need more lift, influencing the pressure and airflow around the wing.
How do birds create lift?
by running and jumping off the ground, also by flapping their wings -Although SOME birds (like the Albatross) have a hard time flapping, THEY HAVE TO WAIT for a strong breeze. Airplanes' wings are thicker at the front of the wing than at the back of the wing. This is in imitation of birds' wings.
How do birds' wings work to enable them to fly?
Birds' wings work by creating lift and thrust. The shape of the wing and the way air flows over and under it generate lift, allowing the bird to stay airborne. The flapping motion of the wings also creates thrust, propelling the bird forward. This combination of lift and thrust enables birds to fly.
What doesnt affect the amount of lift on an airplanes wing?
The best way to answer this question would be to say what does effect the lift of a wing. Pretty much the only things that effect the lift of a wing are the density of the air over the wing, the surface area of the wing, the speed of air over the wing and the angle of attack. Everything else has no effect on the amount of lift on a wing.
Does the shape of an airfoil cause the top of an airplane wing to travel faster or slower than the air underneath the wing?
Faster. This is how lift is produced over the surface of the wing because the pressure is decreased over the top surface Lift=Coefficient of lift x 0.5density of air x speed (squared) x surface area.
