lifting force

Does the net lifting force of the air on the wings increase or decrease?

The lifting force is caused by the downward stroke of the wings.

This pressure difference results in an upwards lifting force.

In this simple system, the lifting force is directed in the same direction as the movement of the weight.

The lifting force was so great that they lost control of their craft on its very first test flight on 14 December 1782.

Once this occurs, the aircraft will climb to a higher altitude until the lifting force and weight are again in balance.

In addition, the harness may provide lifting force to simulate free-body flight.

This provides the rest of the upward lifting force required to support the weight of the tower.

A hook may have one or more built-in pulleys to amplify the lifting force.

As a particular case, a lifting force is accompanied by a downward deflection of the air-flow.

Replies: The downward force decreases, and the net lifting force increases.

Due to the consumption of gas, the lifting force decreased, so the range of the airship had been limited.

Abruptly, the lifting force gave way.

The wing deflects air downward as the aircraft moves forward, generating lifting force to support it in flight.

Recent studies have also shown that the lifting force quickly adapts to the true mass of the objects, but the size-weight illusion remains.

The inquiry has also focused on the plane's wing flaps, which produce lifting forces at takeoff and landing.

Generally, thunderstorms require three conditions to form: moisture, an unstable airmass, and a lifting force (heat).

He posited that a gyroscope set at various angles could provide a lifting force, defying gravity.

Usually accomplished with a skirt on the disc so that the fluid passing the seat suddenly affects a larger area and creates more lifting force.

When Earthwinds lifted off today, it weighed 22,550 pounds, which had to be countered by an equivalent lifting force of helium.

"Each vortex is a low-pressure area that kind of sucks the wing upward, creating an extra lifting force," he said.

The mere act of lifting a thing weighing perhaps ten pounds on Earth, here required a lifting force of more than half a ton!

Counter-balance weights were used to reduce the necessary lifting force, but leaving sufficient unbalance for the gates to be shut by gravity.

The relatively low pressure that exerts the lifting force against the piston is about the same as the air pressure in automobile tires.

In some cases the lifting force is provided by magnetic levitation, but there is a mechanical support bearing little load that provides stability.
