An asymmetric relation is a binary relation defined on a set of elements such that if holds for elements and , then must be false. Stated differently, an asymmetric relation is characterized by a necessary absence of symmetry of the relation in the opposite direction.
On a powerful propeller-driven aircraft, the engine torque driving the propeller creates an equal and opposite torque on the engine itself. Because the engine is fixed to the airframe, this reactive torque is transmitted to the aircraft, causing a tendency to roll in the opposite direction to the propeller.
Dissymmetry of lift [1]: 2–20 [2] (also known as asymmetry of lift [3]: 342 [4] or asymmetric lift [5] [6]) in rotorcraft aerodynamics refers to an unequal amount of lift on opposite sides of the rotor disc. It is a phenomenon that affects single-rotor helicopters and autogyros in forward flight.
The asymmetric transmission phenomenon arises from different, e.g. left-to-right, circular polarization conversion efficiencies for opposite propagation directions of the incident wave and therefore the effect is referred to as circular conversion dichroism.
Asymmetric warfare (or asymmetric engagement) is a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents , terrorist groups , or resistance militias operating within territory mostly controlled by the superior force.
Starbucks has used its image of a double-tailed siren since the early 1970s, but as the company has grown, she has undergone a number of changes.. While many of the alterations simply involved ...
If the axial surface is vertical and the angles on each side of the fold are equivalent, then the anticline is symmetrical. If the axial plane is tilted or offset, then the anticline is asymmetrical. An anticline that is cylindrical has a well-defined axial surface, whereas non-cylindrical anticlines are too complex to have a single axial plane.
The opposite of symmetry is asymmetry, which refers to the absence of symmetry. In mathematics In geometry ... create a symmetric or asymmetrical design, determine ...
