In this diagram, the red team is executing a left wing lock. The left wing lock is a defensive ice hockey strategy similar to the neutral zone trap. In the most basic form, once puck possession changes, the left wing moves back in line with the defencemen. Each defender (including the left winger) plays a zone defence and is responsible for a ...
Paraglider wing, in which a load is distributed by multiple strings, but without rigid elements.

In this diagram, the red team is executing a neutral zone trap resulting in the blue team dumping the puck in. The neutral zone trap (often referred to as simply the trap) is a defensive strategy used in ice hockey to prevent an opposing team from proceeding through the neutral zone (the area between the blue lines) and to force turnovers.
A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the aileron control in this way causes the left wing to drop and the right wing to rise. This causes the aircraft to roll to the left and begin to turn to the left. Centering the control returns the ailerons to the neutral position, maintaining the bank angle ...
Gimbal lock is the loss of one degree of freedom in a multi-dimensional mechanism at certain alignments of the axes. In a three-dimensional three- gimbal mechanism, gimbal lock occurs when the axes of two of the gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
On 23 May 1974, Saturn Airways Lockheed L-100-30 Hercules registration N14ST was en-route from Alameda, California to Indianapolis when the left wing failed due to metal fatigue, causing the aircraft to crash near Springfield, Illinois. Three crew and a Navy courier perished and the aircraft was destroyed. [44] [45] [46]
The position of a swept wing along the fuselage has to be such that the lift from the wing root, well forward of the aircraft center of gravity (c.g.), must be balanced by the wing tip, well aft of the c.g. [68] If the tip stalls first the balance of the aircraft is upset causing dangerous nose pitch up. Swept wings have to incorporate features ...
Joined wing: a tandem-wing layout in which the front low wing sweeps back and/or the rear high wing sweeps forwards such that they join at or near the tips to form a continuous surface in a hollow diamond or triangle shape. [7] The Ligeti Stratos is a rare example. [8] Rhomboidal wing: a
