Bernoulli's principle states that as the speed of a moving fluid increases, the pressure exerted by the fluid decreases.

∙ 7y agoBernoulli's principle states that in a perfect fluid, an increase in speed and a decrease in pressure occur simultaneously. What this means is that when the flow of a fluid is sped up, there is a low pressure area formed. The convex portion of a wing, or other Bernoulli effect inducing structure, causes a diversion of fluid in such a way that the fluid will travel the same linear distance in the same time as if the obstruction were not there. Because the bottom of a wing is flat, there is no change in pressure below the wing, but above the wing there is a protrusion, which causes a low pressure above the wing. as a fluid of low viscosity, air rushes to fill the gap by the shortest possible path, which would be directly through the wing. therefore, you get an upward force pushing on the bottom of the wing. Without these all four forces. If any of birds, insects, and planes does not have any of 4 forces. Its cannot be flight.

∙ 10y agoBernoulli's Principle states that when a Fluid flows past an Orifice the pressure at the Orifice is REDUCED (or drops).
You can see this effect by placing a clear straw in a glass of Liquid and then BLOWING across the opening of the straw. The Fluid will RISE up in the tube due to the REDUCED PRESSURE in the straw.

How does Bernoulli's principle explain how planes lift into the air?
Pressure is inversely Proportional to the Velocity of a Fluid over a surface. This a Corollary of Bernoulli's Principle. A Wing is designed so that the BOTTOM side has a Shorter Distance from Leading Edge to Trailing Edge than the TOP side. Therefore the AIR flow over the TOP has a LOWER Pressure than the AIR Flow over the BOTTOM side. Therefore the WING is being PUSHED UP by the greater Force on the UNDERSIDE. This is called LIFT.
How does a crane demonstrate the principle of moments?
When a crane caries an object, and that it floats in the air. In order to counter that force to lift the object, a counter weight is found at the back of the crane. thus when the crane is not moving, anti-clockwise force = clockwise force.
What fluid opposes lift?
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
An upward force on a plane is called?
'Lift' is an upward force on a plane. Upward force on a bird's wings is also called 'Lift'.
What Principle explains the operation of a hydraulic lift system?
Pascals
Evaluate would a 9n force applied 2m from the fulcrum lift the wight explain?
A 9-N force cannot be applied 2 m from the fulcrum lift the weight because it wouldn't balance
How does an airplane get lift during take off?
As the airplane speeds up the air flowing around the control surfaces speeds up as well. When this happens the horizontal stabilizer is deflected into the wind causing the nose of the aircraft to rise. As the nose rises the angle of the wings also increases and create lift by 'air deflection' and 'bernoullis principle'. Many other factors are involved to create lift, these are just the main principles.

Who explained the operation of a hydraulic lift system?
Bernoulli's principle. The above answer is wrong. Its Pascal's Principle :)

How do you lift heavy objects efficiently?
By using the principle of levers.
What Principle explains the operation of a hydraulic lift system?
Pascals
What is force of lift and thrust?
Lift is the force that acts upwards, perpendicular to the chord of the wing. Thrust is the force acting perpendicular to the propeller disc.
What force gets a plane into the air is?
the force is lift
How do the rotors on a windmill and the sail of a sailboat illustrate the same principle?
The principle of lift is well-illustrated by the motion it causes.
