If the insect flaps its wings at a slow rate, the time interval during which the lifting force is zero is longer, and therefore the insect falls farther than if its wings were beating rapidly.

:: : I checked there, and it seems that all you did was compute the lifting force for an estimated volume of hydrogen, and the assumed that the craft + rider must weigh more than that.
33.
They are often used where a powerful hydraulic jack is required, but there is insufficient space to fit the cylinder size that would normally be required, for the lifting force necessary and with the available system pressure.
34.
If the device jammed in a nose-up position, a crew could compensate by banking and putting the plane into a turn, which would turn the lifting force of the wings somewhat to the side, making the nose fall.
35.
If the device jammed in a nose-up position, a crew could temporarily compensate by banking and putting the plane into a turn, which would turn the lifting force of the wings somewhat to the side, making the nose fall.
36.
BC attachment systems are generally intended to limit the shifting of the BC as a result of the lifting forces, including minimizing the tendency to slide towards the head when the diver is upright while the bladder is inflated.
37.
The top plate of the bellows is ballasted, so that the lifting force of the air inside is balanced by the weights : when the diver is trimmed horizontally, face down, the weights create a slight positive pressure relative to ambient.
38.
In addition, church artists increasingly showed angels with ever more accurate depictions of bird-like wings, detailing the wing's camber ( curvature ) that would prove beneficial to generating the lifting forces enabling a bird & ndash; or an aeroplane & ndash; to fly.
39.
The two primary issues involved in magnetic levitation are " lifting forces " : providing an upward force sufficient to counteract gravity, and " stability " : ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized.
40.
For takeoff, the entire outer part of the wing could be rotated 90 degrees so that the propellers is directed straight up so that they would create a lifting force that would left the aircraft off the ground in a manner similar to that of a helicopter.
