liftUpward-acting force on an aircraft wing or airfoil. An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force. The lift force arises because the speed at which the displaced air moves over the top of the airfoil (and over the top of the attached boundary layer) is greater than the speed at which it moves over the bottom and because the pressure acting on the airfoil from below is therefore greater than the pressure from above. |

| He had lingered outside the lift in the entrance hall waiting for the lift-boy, who generally conducts strangers to the various floors. You percave the little spalpeen is summat down in the mouth, and wears his lift hand in a sling, and it's for that same thing, by yur lave, that I'm going to give you the good rason. But when I dream of thee apart, I would the dawn might lift my heart, O sun, to thee. |
