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.
Triangle is still the most common. The shape cuts into the wind with little to no resistance and then spans out to create lift. This also gives the kite direction. Airplanes have the same general shape.
An average 3 ton mini excavator will lift approx 1400kg, almost half the weight of the machine as a general rule of thumb
Generally, lift is created when the pressure below an object is greater than the pressure above it. For example: an airplane wing is curved on top to allow for air to seamlessly pass over, creating low pressure on the upper surface and the wing is obstructed on the bottom, creating higher pressure to lift the wing. As for a helicopter, the air is pushed down by the propeller, causing high pressure below the rotation plane, causing lift.
The 4 main forces of flight are: drag, thrust, lift and weight
It was made by John W. Parker in California.
Birds have streamlined wings that create lift and reduce drag, allowing them to efficiently glide and soar through the air. Bats have flexible wings with multiple joints that can change shape and surface area, providing maneuverability and agility in flight. Both adaptations help birds and bats generate lift and thrust to fly effectively.
The wings and horizontal tail surfaces create lift.
God
The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
All birds fly only right-side-up. In order to create lift, they must flap their wings down, and they are specially shaped for this.
Birds do not lift weights.
the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
Lift! The wings on a plane create an upward lift.
No, birds do not fly because of a magnetic field. Birds fly by using their wings to generate lift and thrust. They navigate using a variety of cues, including landmarks, the position of the sun and stars, and Earth's magnetic field.
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.
If they were flat they would generate no lift and birds could not fly. Aeroplane wings are very similar in shape to bird wings - they are nearly flat underneath and convex on top.
If the lorry contains the birds in a sealed container then the weight is unchanged. As they lift from their perches they must accelerate and the resultant downward force on the lorry will make it appear to weigh more for a very short time.
