Lift is a phenomenon whereby a uniform flow in one direction produces a component of force on an obstacle in a perpendicular direction. Aeroplane wings and automobile spoilers are examples of cambered ...

Even in 1800, it was understood—by at least one person, a certain George Cayley—that two forces, weight and drag, were antagonistic to flight and that there must be two corresponding forces to ...

There are many ways to describe the forces around sails — in fact, around any foil. One of the most straightforward ways is to split the forces into lift and drag. The lift force is, by definition, ...

Light has been put to work generating the same force that makes airplanes fly, a study appearing online December 5 in Nature Photonics shows. With the right design, a uniform stream of light has ...

Ever find yourself sitting in an aeroplane and marvelling at how something so heavy can just float high above the ground? For ...
