For smaller structures ( like houses ), roof is often a lifting force in winds requiring many steel straps to the foundation through other tensile structures like wooden frames.
22.
A variable system that uses " active fins " designed specifically for roll attenuation of a vessel while underway achieves lifting force through the flow of water over the fin's surface.
23.
With 2, 460 kilograms gross weight at launch and 2, 600 kilograms initial lifting force, it was expected to fully expand at 17, 700 metres and reach static equilibrium at 19, 500.
24.
In summary, depending on whether the icing event occurs on the wing or horizontal stabilizer / stabilator, the lifting force that is deceased can result in a pitch up or pitch down.
25.
By passing heavy cables under a wreck and connecting them to two hulks, a wreck could be raised using the lifting force of the tide or by changing the buoyancy of the hulks.
26.
The main purpose of the circulation control wing is to increase the lifting force of an aircraft at times when large lifting forces at low speeds are required, such as takeoff and landing.
27.

28.
:: : : : Any increase in air pressure within a " sealed " container will exert just as much lifting force on the roof as it will depressing force on the floor.
29.
To simplify the calculations, one must assume that the lifting force is at a finite constant value while the wings are moving down and that it is zero while the wings are moving up.
30.
The edge of the aileron directs air flow from the under-side of the wing to the upper surface of the aileron, thus creating a lifting force, which adds to the lift of the wing.
